But why? The cost of attendance in life is death. And each and everyone of us already payed this price. So what's the point here?

Imo if you aren't able to gut some pain, you aren't fit for life. Life for most parts is pain in one or another way and the earlier one accepts this fact the earlier one is actually able to live in the present instead of filming it with a "smart"phone to "uplift" their own ego for likes.

When you let go, things can go wrong. Seems very natural to me.
