If you want to be richer than Bill Gate, invent the curable medicine of dibetic.?

Some people say nothing is impossible but curable medicine for diabetic, artharities, HIV and blood pressure are still not invented. There are still greater opportunities to be trillioner for all , who says noting is impossible. I am not saying make a man immortal or make us as young as we were but there are still possiblities to invent and to become rich despite spending in war and gun.
