Would i have been taller?

I' m a 15 year old male who is 5" 10" which is average for my age. I don't take care of my health. I don't eat healthy nutritious food, or excersice, or even get full 8 hr of sleep. I don't do any of that. Would I have been taller if I actually had done all this when I was young or doesn't effect it at all?
