"why are most males from western countries going bald in their thirties"? is correct.... I think its a european thing. I have no idea. As you can see from my picture, I am not affected (hehehe)

I don't think most western males begin to go bald in their thirties. Some do. And some do even earlier. But it's certainly not the majority.

I don't think this is necessary the rule here. If you look at South Asia, India, you will see that many if not the majority of males are bolding in their 30's. This is mainly a hereditary issue and being that the "West" is very diverse, applies to different groups of people in a different way.
