Male Baldness Info

I just discovered that I’m going bald… my mother who is a hairstylist and has been cutting my hair since I was a boy pointed it out to me… I’m 20 years old… she says my father was showing baldness by the time he was 25…
I’m also fat…
So… do I have enough time to get married and then divorced like everyone else? Or will I be the epitome of an inferior male specimen when its too late…

Im 15, male, and I swear I’m going bald. There’s a history of baldness in my family, so I knew I going to eventually, but I’m only bloody 15!
My hair has always been flat, straight and not particularly thick, but around the crown and down the back it’s seeming to get thin, and you can really REALLY see the lines if I rough up the back and there’s lights on (and even if there isn’t).
It might seem trivial but it’s really killing me. My dad started properly going bald when he was 25, but for my uncle it was about 30-35 and my granddad was closer to 40 I think.
Am I being stupid? And is there anyway to fight it off?
Also, things such as baldness following your maternal side isn’t true, it’s both sides. Trust me, most of my family is living proof.
