Well my 2nd cousin had full chest hair by the time he was 13.
Mostly between the ages of 10 and 13
Boys typically grow the fastest between the ages of 11 and 13. Most boys stop growing at around 16.
not all hairy men are bald That is correct, but I have noticed that men older than 30 who are really hairy on their chests and arms, tend to thin out on head, so by the time they are 40 many are bald on top, something to do with genes in them. Many men who have won hairy chest competitions are completely bald on the head. I have never entered a hairy chest competition, I do have a hairy chest, but not thick enough to win a competition, but I do have still at 66 years of age a reasonable amount of hair on top of my head, thinner, but still a lot, I am not bald.
Boys typically start getting chest hair during puberty, which generally occurs between the ages of 9 and 14. The timing can vary from person to person, and genetics play a role in determining when this secondary sexual characteristic will develop.

You are a idiot. They Dont.
Women usually grow until they are around the age of sixteen. Boys usually grow until they around the age of eighteen.
Your body starts to grow quicker during Puberty. This can begin from age 10 for girls and 12 for boys.
It varies dramatically. A few men will have a thick mat of chest hair before they are 18; other men are relatively smooth-chested in their teens and 20s and then develop a lot of chest hair in their 30s. Typically, however, you should have a sense for how hairy your chest will be by the age of 25 or so.
Because they ARE boys, and they do not grow up until at least the age of fifty. Then only after a good wife has trained them.
None; chest hair and body hair are determined by genetics and age and by nothing else. If the adult men in your family have chest hair, then you probably will get some too--though in many men chest hair doesn't grow in, or grow in fully, until their 30s.
Boys typically start to grow facial hair, including a beard, during puberty, which typically occurs between the ages of 12 and 16. The exact age can vary depending on individual genetics and hormonal levels.
