"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 fall of 1959, Freed suffered a bad reputation for rumors of bribery (贿赂行为), and his troubles were too strong to be resisted. When WABC asked Freed to sign a statement swearing that he had never taken bribes, he refused and was fired. Although he later signed such a statement for WNEW-TV, he lost his television show as well.

    Finding himself unwelcome in New York, Freed fled to the West Coast, where he managed to land a daytime disc jockey (流行音乐播音员) job at KDAY in Los Angeles in 1960. Legal problems continued to bother him, though, and he was charged with taking bribes of more than $30,000 from a number of record companies. Publicly, Freed denied that he had ever accepted direct bribes, although he acknowledged that he had accepted gifts from record companies, but only for playing records that he was certain would become hits anyway. After a short time at KDAY, he left when the station management refused to let him promote his live rock ‘n' roll shows. He returned to New York, but not as a broadcaster. At the height of the great enthusiasm for the twist dance, he hosted a Manhattan twist revue (时事讽刺剧), but when this enthusiasm cooled, he found a disc jockey job at WQAM in Miami in 1962. During this difficult period, Freed began drinking heavily and lost his job in Miami after only two months. In December of 1962 he was found guilty in New York of two charges of commercial bribery and was given a six-month sentence and fined $300. This effectively ended his career.

    Freed spent the last years of his life in Palm Springs, California. Although he had redefined what it meant to be a disc jockey and named the music that had become an anthem (圣歌) for the world's youth, he was a disgraced (耻辱的) and broken man, no longer able to work in the business he loved. On January 20, 1965, he died in a hospital in Palm Springs.

    Truman headed home from school, with the homework in mind, a report on beehives (蜂巢). Truman's class had studied bees for three days, so he was ready. But, as his teacher Mrs. Lawrence had explained, to earn an A +，he needed a “new angle”.

    Truman pushed open the front door to find his four-year-old brother, Bryan, sitting on the living room rag, hard at work. Paper towel tubes were all over the floor.

    Bryan quickly stood up. “Truman, help me build a city!”

    “I'd like to,” Truman replied, “but I have to do a report on beehives and ...”

    “Can I help you?” Bryan begged.

    “I don't think so, Bry. Sorry.''

    “I know where there's a beehive.” Bryan smiled.

    “Where?”

    “In the wood pile by the garage.''

    The boys marched to the firewood. Bending down, Bryan pointed out the hive deep inside the pile. Truman carefully removed the hive out.

    “You got it!” Bryan shouted.

    Back in the living room, Truman paced around, turning the fragile hive under his nose. Each cell was a perfect hexagon(六边形). How did the bees fit the cells together so neatly? And how did they make each cell six-sided? Could they count? Lost in thought, his foot came down on something ...

    “Truman! You're mining my city!”

    “Get your stupid tubes out of here，Bryan! I'm trying to…”

    The towel tubes on the floor suddenly reminded him of something. The beehive!

    Looking closer, he noticed the tubes were arranged with one in the middle, surrounded by six others, just like the cells of the hive.

    Just to be sure, he tried five and then seven tubes surrounding the center tubes, but neither way fit. Six was the only number that worked.

    “Bees don't count to six,” he said aloud. “The cells have to be six-sided.

    Truman ran to Bryan and threw his arms around his brother. Bryan, you did it! Now I can build a model beehive with your tubes! I mean — if it's O. K. with you.”

    I was ever bullied badly when I was in high school. One kid in particular would try to make me feel worse in every way he knew. For example, he would throw stuff at me constantly, hit me on the head, punch(殴打)me, call me ugly and stupid, make fun of me and, of course tell me he would beat me up if I ever fought back. It was like his daily mission.

    And it was my daily mission to just get through the day. What could I say? It made my world very small because that was my main focus- just surviving. Everything else fell by the wayside. Unfortunately, that included any form of social life. So not only was my world tiny, but it was very lonely

    Looking back to that time, which was about 11years ago, my biggest mistake was not bringing anyone into that world of mine. I was too proud (and embarrassed) to get help. I would rather not face the fact that I needed help because in my mind, that would mean that the bully won. It would also mean that I was weak.

    Let me just say this: bullying someone is a weak choice. The only reason why they come after you is that they think you won't do anything about it. Does that make anyone strong? Absolutely not. Be stronger-ask a parent, a teacher or a friend for help. Simply admit that you are struggling and need help.

    You can put it like this, "Somebody who is weak and trying to build himself or herself up has chosen to do that by putting me down. The only reason why they are doing that is that I am nice and I haven't done anything about it yet. Well I am through putting up with this. I have basic human rights that they are trying to take away to feel better and that is just not OK. How do I handle this? I don't want the pain cycle to continue and I don't want to become someone I don't want to be.

Tests have shown robots can diagnose heart problems in as little as four seconds, as a review of artificial intelligence (AI) finds machines are now as good at spotting illness as doctors.

Analyzing a patient's heart function on a cardiac MRI (心脏磁共振成像) scan currently takes doctors around 13 minutes. But a new trial by University College London (UCL) showed an AI program could read the scans in less time with equal accuracy. There are approximately 150,000 such scans performed in the UK each year, and researchers estimate that fully using AI to read them could save 54 clinician-days (临床天数) at each cardiac centre per year. So it can make up for the shortage of doctors.

It is hoped that AI where computer systems are able to learn from data to identify new patterns with minimal human intervention will transform medicine by helping doctors spot diseases such as heart disease and cancer faster and earlier. However, most scans are still read by specially trained doctors.

Dr Charlotte Manisty, who led the UCL research, said, "Cardiovascular MRI offers in- comparable image quality for assessing heart structure and function. However, current manual analysis remains basic and outdated. Automated machine techniques offer the potential to change this and completely improve efficiency and accuracy, and we look forward to further research that could confirm the superiority to human analysis."

She added, "Our dataset of patients with a range of heart disease who received scans enabled us to demonstrate that the greatest sources of measurement errors arise from human factors. This indicates that automated techniques are at least as good as humans, with the potential soon to be 'super-human'—transforming clinical and research measurement precision."

Professor Alastair Denniston said, "Within those handful of high-quality studies, we found that by deep learning AI could indeed detect disease ranging from cancer to eye disease as accurately as health professionals. But it's important to note that it did not absolutely exceed human professional diagnosis. "
