Answer 1

Don't worry, you keep abusing your body and you will be sick in years to come, really sick. You might get bowel cancer or pancreatic cancer. Then you will wish you hadn't been so stupid when you were younger.  

Answer 2

wow :) Well, you're young now - but you won't be able to continue like this. Sooner or later you'll start feeling the consequences
