42 going on 22, I've barely changed since then tbh. Age is just a number. Still can't grow a full beard yet and I don't have the type of stubble/face or whatever that can't ever grow a full beard its just taken me this long to mature physically. I still remember a kid in school growing a full beard at around 14. I'm only 30 years behind can you believe that?
I was a bit immature when younger but that's partly as I must be a late developer.
