2. Curves and bumps are part of our life.
When you drive on a smooth highway, how do you feel? Good. That’s true.
But you tend to be sleepy after some time. And it’s dangerous to feel sleepy while you’re driving.
So, there are bumps on the road, to help us awake. The ride will not as smooth as the normal road, but we are more aware after that.
The same thing with curves along slopes. It slows down our driving, but the effort is lesser than if we don’t her curves.
Same thing with our live, we need those too.
