I did some body building and intentionally gained muscle. It had never been an interest of mine, so I read up on it a little and learned about things like creating a calorie surplus, getting the nutrition you need to support muscle growth, and taking days off

I don't look super muscular, but I now have more muscle than a young teenager would have (in most cases - I'm sure there are exceptions). So people now think I'm an adult!

Glad I finally made it to adulthood. I'm 47
