Bald problem

I always worry about this....Bald problem that seems like every men will face.
When I shopping with my girlfriend..or simply out to lunch...I always observe ppl around.
No matter he's a man or women, fat or thin, tall or short.
I like watching ppl...

Recently, I start notice uncle around...
I found that..almost 9/10 having bald problem.
But some uncle really smart, they bald, but they shave all their hair.
Turning from ugly bald to kinda cool "botak".

The uncle I mean here doesn't always pointing to those 40 or 50 above.
Some looks quite young like maybe only 30+ but already start bald.
Again, they always just shave off all their hair, make it completely no hair.

I heard ppl says that men's hormone (testerone) causing this problem ---> BALD.
I was wondering, in this case, does it means those hairy mens will always have this problem compare to those mens that not really hairy?
For those who has hairy hands....hairy back...hairy chest...Yes, I mean you Mr.A :P.
Aware lor~hahaha.

Anyway, I'm worry about this problem too...
I asked two hair stylers whether I'm suitable to fully bald or not.
They like those auntie uncle in the market buying watermelon, "roll" my head around and told me : "Nope, ur head shape is not suitable for that."
Hmm...bad news for me actually, cos I'm thinking to shave off my hair, at least when the time I really having bald problem, I can shave my hair and looks cool. :(

The idea of shaving my head start winding me again recently, still need courage in doing this....
Do you think I should shave my hair??
Worry.....
