Why it's so hard to make healthy decisions
Summary
Why is it so hard to make healthy decisions?
It’s because it’s strongly thought that humans must have the most rational move of all and they’re all constantly calculating the costs and benefits of every one of our actions to make the perfect right, however, it hasn’t been right.

Our actions are always irrational, even we know that it’s wrong. The fine doesn’t work well also. Car accidents are dangerous, though, people sometimes don’t use seatbelts. People want to be slim, though, they eat chocolate a lot. People know that spreading diseases have to be stopped, though, they don’t wash their hands sometimes. People believe that not buying lotteries makes them regret.

We fundamentally care what others think of us, though, we seem to be irrational.
