Why is so popular among teenagers?

Because humans are advancing to understand faster and faster the fact that their teenage bodies are not going to last forever and so they are more trying to not take it for granted all the fun they might have as they have confidence in their futures that they will overcome all their youthful faults. The bad thing about this is that it leads to early parenthood and drug addiction that can subside only after it is too late and that confidence in the future is overlapped with guilt and shame.
