The Science of Risk-Seeking

    Sometimes we decide that a little unnecessary danger is worth it because when we weigh the risk and the reward, the risk seems worth taking. {#blank#}1{#/blank#} Some of us enjoy activities that would surprise and scare the rest of us. Why? Experts say it may have to do with how our brains work?

    The reason why any of us take any risks al all might have to do with early humans. Risk-takers were better at hunting, fighting, or exploring. {#blank#}2{#/blank#} As the quality of risk-taking was passed from one generation to the next, humans ended up with a sense of adventure and a tolerance for risk.

    So why aren't we all jumping out of airplanes then? Well, even 200,000 years ago, too much risk-taking could get one killed. A few daring survived, though, along with a few stay-in-the-cave types. As a result, humans developed a range of character types that still exists today. So maybe you love car racing, or maybe you hate it. {#blank#}3{#/blank#}

    No matter where you are on the risk-seeking range, scientists say that your willingness to take risks increases during your teenage years. {#blank#}4{#/blank#} To help you do that, your brain increases your hunger for new experiences. New experiences often mean taking some risks, so your brain raises your tolerance for risk as well.

    {#blank#}5{#/blank#} For the risk-seekers a part of the brain related to pleasure becomes active, while for the rest of us, a part of the brain related to fear becomes active.

    As experts continue to study the science of risk-seeking, we'll continue to hit the mountains, the waves or the shallow end of the pool.

A. It all depends on your character.

B. Those are the risks you should jump to take.

C. Being better at those things meant a greater chance of survival.

D. Thus, these well-equipped people survived because they were the fittest.

E. This is when you start to move away from your family and into the bigger world.

F. However, we are not all using the same reference standard to weigh risks and rewards.

G. New brain research suggests our brains work differently when we face a nervous situation.

    We all wish we had just a bit more time. Just think what you could do with an extra hour or two each day: you could finally stick to an exercise routine, or spring­clean the house, or write your novel, or learn the guitar and so on.

    {#blank#}1{#/blank#} But I can help you find more hours in your day for the things that really matter.

    Get Out of Bed Earlier

    If you normally get up at 7：30 a．m., try getting up at 7：00 a．m. That half­hour might not sound like much, but it could be time that you use to exercise, to read that book you've been meaning to finish. {#blank#}2{#/blank#}

    Do the Important Tasks First

    Once you get to work, get the important ones done first (not the easy ones, or even the urgent ones). You can afford to spend at least an hour working on big, important tasks rather than on all those little urgent ones.

    {#blank#}3{#/blank#} The urgent tasks will still get done, and you won't miss the important ones.

    Reduce Interruptions

    If colleagues have a habit of hanging around your desk to chat, or if the phone is constantly ringing, you might find that it takes you half the day to finish a simple task like writing a letter. Constant interruptions don't just eat up time, they also break your concentration.

    When you've got a big task to focus on, let your calls go to voicemail. {#blank#}4{#/blank#} Wearing headphones makes it less likely that people will try to strike up a conversation.

    {#blank#}5{#/blank#}

    A few minutes' chatting, browsing the web, and so on, can easily turn into hours of wasted time over the course of a day.

    When you're working, work. If your concentration is slipping, take a proper break: go and get a glass of water, or stretch your legs a bit. And if you're facing a difficult task, try breaking it into small steps or stages so that it's easier to deal with.

A．Stay Focused on Your Work

B．Take Breaks When Necessary

C．If you have an office door, close it.

D．If you work like this, you'll usually save time.

E．Would you want me to make your day longer?

F．I can't magically make all your days 25 hours long.

G．Or simply to get your day off to a calm and organized start.
