怕痒痒的人，不怕谁挠痒痒？
人在什么年纪最聪明？
心脏真的在人体左边吗？
Fact One:
No matter how ticklish you are, it's impossible to tickle yourself since you're expecting it and your brain processes it differently.
不管你有多怕痒，自己是不可能挠自己痒痒的。因为大脑会有准备且处理方式不同。
Fact Two:
Your brain is at its peak when you're in your late 40's. If you haven't reached that point yet, don't worry because you've got time to get even smarter.
大脑在人48，49岁时会达到顶峰。如果你还没到那个岁数，还有变得更聪明的机会。
Fact Three:
Contrary to popular belief, the heart is in the middle of your chest, between the right and left lungs. However, it tilts slightly to the left, creating the illusion it is in the left side.
与大众认识不同，心脏其实在两个肺的正中间。然而它稍向左偏，给人造成在左边的错觉。
