Do muscles or size of a person make them look older?

I am 21y. o.
Weigh 140
And 5'8"

I am a slim guy, always have been, I don't think I'll ever be considered Big and I'm ok with that. But I also have a rather young looking face.

I'm not into heavy lifting, just not my type of exercise. But if I lift a little and do body weight exercises everyday to put on a little more muscle and get my weight to like 155 or so (the healthy way)...

Would I look a any older?
Yes
Probably Not
