Yes because you are becoming a man
Not necessarily, but a young man with hairy arms is more likely to develop chest hair at some point (usually by his early 30s).

Because "hair" is hair ... and having lots of chest hair makes for a hairy chest.
By the time a man is in his 40s, he probably has all the body hair he is ever going to have.
So here's the thing: chest hair is genetically determined. If you look at your father, grandfathers, or uncles, and if they have chest hair, then you might get chest hair, too. If not, then it's less likely. But there's another thing: men continue to develop body hair throughout their 20s and into their 30s. It is entirely possible that a man who has no chair on his chest in his 20s will develop some in his 30s. That said, the fact that you are 28 and have no chest hair so far probably means that you're not going to have much, if any, chest hair--and there is literally nothing that can be done about this. Usually I advise hairy men to be comfortable being hairy and not wax or shave, etc., but in this case I advise you, as a smooth man, to be comfortable being smooth. The fact is that a lot of women (or men, if you are gay) really prefer smooth chests. I say embrace your smooth chest!
You should become a man and wait a few years for some hair to sprout.
Usually, yes. Men don't finish growing all their body hair until well into their 30s, however, so a 20-year-old man with a heavy beard might not have any chest hair--but by the time he is 35 he probably will. (Although the 20-year-old may well have lots of chest hair already.)
One of the fastest ways for someone to remove their chest hair is to have their chest waxed or either to wax their chest themselves. Chest hair removal can be quite painful.
