Is it bad that I'm 17 and still don't drink or smoke like everyone else my age?

I have thanatophobia ( its the fear of death__ I don't ever want to drink because I've seen on the news that it can kill you... I don't want to risk that.. but I'm also very curious, I have never been drunk in my life or drank alchohol, its very tempting when mum or my brother asks me if I want some, but I just can't I'm so scared. As for smoking, its the same, firstly I hate fire and 2nd I don't wanna die, is this okay? a lot of my friends do it. On top of that, I'm scared of learning how to drive because I'm scared I'll die in a car crash, and I'm scared to have sex with someone because I'm scared of stds, is this all okay? or should I stop being a wuss... Instead of smoking or alcohol, I get my happiness from watching cartoons like spongebob and stuff, is that okay?
