Why do people do things that are bad for them?

Low self-esteem.

People who value themselves lowly are attracted to scumbags in a relationship.

People with poor self-image overeat and indulge in bad habits etc.

If you increase your self-esteem, you will be more attracted to fruit and vegetables and exercise, and you won't feel tempted by junk food at all.

Why did you ask a question that almost has no answer available to it? Why ask a useless question?

You probably did it for the same reason most people do the things they do: lack of awareness. Bad is only bad when it's processed and accepted as such. What someone else knows (this question is pointless) and what you know (I think it's important) answers the question why the two shall never meet.

I've actually been wondering this a lot lately. I think humans are imperfect.. therefore they have self-esteem issues and generally turn to doing things/people that are bad for them. It's just a natural part of life.

They do it to look cool, and maybe peer pressure. I mean, if everyone thought doing drugs or whatever is so lame and makes u a loser, than not many people will do it. Also, they might do it because they are depressed, or they want to forget troubles, meaning they don't care about life anymore i guess.

I drink a lot and smoke a pack a day ... pretty much because I enjoy it and because it probably won't hurt me in the near future (I'm 25). Also, because I'm a country guy and that's one of the things we do for fun here

Self-abuse because they like to its another mental problem to rebel but this makes no sense because self-harm doesn't solve any problems or real issues its just silly.

I have damaged myself whilst a young adult I put this down to immaturity and inexperience to other coping strategies or solutions.

A VG question BTW

probably because they enjoy it, or it fulfils some need. For instance, I ride a motorcycle virtually every single day. I could smoke instead, but that doesn't give me the same sort of rush.

By force of habit

well those people want to look like a rebel and look cool therefore they go to extreme limits to make themselves look big and bad, are you crazy i am not tryin to impress anyone except the lord and me!!! and my mama and dad and someothers

coz they wanner a challenge
