The warts are basically because you eat alot of crap.
Let me guess what your diet is:
A glass of milk with nesquik and pan dulce (xtra sugar) as breakfast to start the day, coca-cola is your replacement for water and Asado (argentine version of a barbecue) every weekends. In addition to this you´d probably be constanly having flue-like symptoms even in the summer.
That´s the main reason you got warts at age 16. You were too hedonistic in your diet; taking the things that taste sweet as your judgement for choosing food. I know because I got my wart removed (burned off with a laser) at the hands of an "expert" allopathic surgeon at the same age. And the only reason for that was the extra-meat Argentine cultured diet that is an on-slaught to the digstive system. The barbeque diet is why I was contipated for years on end, having no more than two bowel movemnts per week and thinking that was normal. The warts are simply due to constipation, my friend!!
