Why do people drink as if there is no tomorrow?

You are doing the right things there my friend.Do not be tired to keep giving guidance to your two cousins whom you said are frequent drunkards,especially the 19 years old,whom I taught is already old enough to think what is good or bad for his sake.If he still do not listen to you,just wait for him when he is not drunk,and let him hear that it would be your last reminder for him.Tell him ,that he is already old enough to be reminded that life would never be back and he must finish his studies first and his vices as to a drunkard should be stop,so that he can get serious to his studies.Let him just think that the money spend for him could never be useful if he just keep on drinking,and may not have the chance to finish his studies if he is not going to get serious,that his parents are already tired to finance his studies. So let him feel that he must be serious in his studies or he could stop to pursue his wish to become a professional.I think by doing this,he would listen to your reminder and would lessen his being a drunkard.

people drink sometimes to enjoy , sometimes to avoid depression and sometimes to show their status...... but they forget that losers only drink.. how educated they may be , but by drinking they start making their life a waste by their own hand.

I think people drink because they think it's the only way to have fun. Drinking has always been portrayed as the go-to for having fun, but today's culture really puts emphasis on drinking and partying. Also if you don't drink you're seen as a prude so peer pressure plays a part too .
