"Some secrets are hidden from health," wrote John Updike in his poem "Fever".

    I have experienced the truth of Updike's observation. My excellent health kept me from seeing some things—things that became secrets of sort.

    One relates to my son Chris. When I lost my health in March, I discovered something I had missed about him.

    Christopher has been a scholar and athlete through high school. He has behaved responsibly, engaged in community service. He has had an impressive peer group of  serious students.

    While I saw these things, I had missed before what I experienced while in hospital. Early on, Christopher offered the clearest and most forceful words about my need to be positive and to fight acute leukemia(急性白血病). He never left the room after a visit without making me promise that I would be mentally tough and positive.

    During the first week, he showed his own mental toughness, researching leukemia and learning what the chances were. He even stopped my doctor outside the room, introduced himself and asked directly what he thought of my chances. He processed the answer without overreaction.

    Christopher did admonish(劝告) me against my choice of words the first week at home. I had moved back into my room from weighing myself, discovering a thin figure I did not know. I announced to him and my wife, “dead man walking”. I thought it was a way to lighten the obvious. He saw it as negativity and was strongly against such thinking and talking.

    When I resisted taking medicine sometimes, Christopher formed a “good-cop-bad-cop” team with his mother. Betsy gently and patiently encouraged. He directly and forcefully insisted. He always made the logical arguments for why I needed to take some awful pills.

    My health had hidden something from me; my ill-health helped me to see it.

    In the early times,the music industry was terrified of taping,thinking that customers would just copy music,or record from the radio.But that never really happened,at least not enough to cause any real hardship to anyone in the music business.

    The same argument arose over technologies like miniDisc and recordable CDs.But the thing that terrified the music industry more than anything else was the arrival of services like Napster,which allowed people to share music over the Internet without costing them anything.The music industry was shocked: it saw people exchanging digital copies that didn't degrade（降级）with each transfer,something that kept tapes from being a huge threat.

    But it wasn't the Internet that killed the music industry.In fact,everything is still looking optimistic for many musicians.Taylor Swift has had a good year,and her latest album is likely to be making her very wealthy indeed.And that won't change in all likelihood,not for Swift,and not for those who come after her.There is always going to be public demand for music.

    However,the technology will simply destroy the record company.The reason is simple.Record companies are a man in the middle that simply doesn't need to exist anymore.The same way we buy our flights directly did get our shopping online and have things delivered from Amazon instead of going to a local shop.We have always been willing to enjoy cost reductions at the expense of the middleman and the record companies are that kind of middleman.

    What does the record industry offer?Well,surprisingly little these days.It used to be the case that record companies would go and find new talents.Of course this still happens,but more likely is that an artist will be discovered by the public through YouTube,or even from friends on Facebook or Twitter.Record companies also used to have an important role in producing the music.But countless artists are making their own way through software or any of the other amazing music development apps,without any help from the record companies.

    Growing up in the mountainous Sierra de Penamayor, in Asturias, northern Spain, Aladino Montes had been shooting deer ever since he was a child, but his life as a hunter came to an abrupt end 10 years ago, when he met Bambi, an adorable deer that has remained by his side ever since. Aladino has never shot an animal since.

    53-year-old Aladino recalls driving through the mountains in his little jeep, ten years ago, when he saw a couple of cows being followed by a skinny little deer. Deer don't usually hang out with cows, so he approached the animals for a closer look. That's when he noticed that the deer had several wounds and would have probably died without proper medical care. He put the injured animal in his car and drove back to his house where he nursed it back to health. But instead of running back towards the forests, the deer stayed by Aladino's side. They've been best friends ever since.

    He always loved animals, but his father had taught him to hunt deer as a child. He did it for food, not sport, but ever since he adopted Bambi, he hasn't shot a single animal.

    Aladino's cabin sits at 1,140 meters above sea level, offering tourists a beautiful view of the surrounding mountainside. On clear days, one can see all of central Asturias all the way to Gijon, but most people don't travel to Les Praeres for the view, they come to see Bambi, the friendly deer.

    Sometimes, Bambi will walk straight into the bar in search of Aladino and leave everyone with their mouth open, or even let people pet her. But she's always most comfortable at the side of her rescuer. She's so relaxed around him that she makes other deer feel safe as well.

    Times are a little tough at our house right now. Neither of us makes a lot of money, but years of experience have taught us how to walk between the raindrops and make it from one month to the next with a fair amount of grace. I cook a lot at home, more when we're facing difficult times. When I know that I have to keep us fed on not much money, I fall back on my grandmother's recipes. She taught me to cook.

    When I was a kid, my twin brother and I spent long summer weeks and Christmas vacations with my mother's parents in the mountains of North Carolina. Rather than go hunting with my grandfather on mornings, I found myself more and more in the kitchen with my grandmother, watching her making a lemon cheese pie with her soft hands.

    My great-grandmother died when my grandmother was 11 years old. As the eldest daughter, she was expected to take on all of the housework while attending school. Throughout the Great Depression, she learned how to make a little food go a long way. Vegetables were cheap, so she cooked a lot of them, mostly only using small amounts of meat for seasoning. Roast beef was a twice-a-month luxury, but there was nothing she couldn't do with a chicken, every part of it. Nothing went to waste.

    Now I understand that her food was sacred (神圣的). I feel connected to my grandmother and to hundreds of years of family when I'm in my kitchen making country food. In the delicious smells is a long tale of victory over hard times, of conquering starvation of not just surviving, but finding joy and pleasure in every meal of every day.

From grandmother I learned to take real satisfaction in feeding people. My grandmother would beam with pleasure over a heavily laden table and say: "Do you know what this would cost at the restaurant?" I never knew what restaurant in particular she had in mind, but I knew that the question was totally not fair, because no restaurant anywhere can cook like a grandmother. But now, thanks to her guidance and years of practice, I can.

    As people age, the body changes in all sorts of predictable ways. Brains can slow. Wounds take longer to recover. And sleep patterns(模式) shift, too. This can come as news to many, says Michael V. Vitiello, a psychologist at the University of Washington who is expert in sleep in aging.

The most noticeable—and often most annoying—changes are how sleep and wake-up times change and sleep gets lighter, often beginning in middle age. Gone are weekend sleep to 11 a.m. and the ability to sleep through a noisy garbage truck down the block.

But not every restless night can be ignored. Studies have found that poor sleep can create a particular threat to older adults—Falls, depression and anxiety, problems with memory, and increased suicide(自杀) risk are among the effects of sleep issues in this population group that researchers have found. But scientists are still unsure why those risk connections exist.

    What is clear is the connection between good sleep and psychological well-being in older adults. A 2010 study showed us that connection when it came to sleep quality, but sleep quantity didn't show the same effects. And that, experts say, may be the key to understanding sleep as you age. If you're sleeping less, but don't feel negative effects out of bed, the changes you notice may just be normal age-related.

    Over time, Vitiello says, sleep patterns simply change. "A lot of older adults recognize that they don't sleep the same as they did when they were 18, but they can still function and they're OK. And all is well with the universe."

    Recently a friend of mine asked me whether I'd seen the TV series Cook' Table. Of course, I hadn't because I'm not that into food. But I do get hungry for adventures sometimes, so I decided to watch the show. This is when I was introduced to the cook Francis Mallmann.

    He makes choices; he doesn't plan. When he was young, he looked for mentors (导师) and experiences, not books or paths. He honored his roots but embraced the world and sought things and places he didn't know. He isn't content with just one lifestyle and he doesn't bend to expectations. This made me puzzled because I grew up thinking I had to have a plan and have long-term stability in front of me.

    When I saw Mallmann doing what makes him happy, everything changed. I thought to myself, "That's how we're supposed to live." I felt as if I'd stood up from a comfortable fireplace and the blanket of my life just fell to the ground. I submitted my leave of absence application to my employer less than a month later. I'm now full of excitement. I'm leaving my job and a good salary, and I'm going to do things that feed my soul.

    Michael Kernis and Brian Goldman, psychologists at Clayton State University in Georgia, studied the benefits of authenticity (真实性) and being true to yourself. Some of the benefits of following your inner voice include enjoying a strong sense of purpose in life, greater confidence, healthier relationships and strong skills.

    I might soon be hungrier and poorer than I was before but at least I'll be staying true to who I am and I'll get the true freedom.
