I am only 22 and my my hairline is getting fucked up. It's not really noticeable if my hair is a bit longer, but it's getting thinner (i can see my scalp when my hair is wet) and the temples are receding quite a bit.
I agree though, it's probably best not to worry about it and get a short cut or shave it off.
Just sucks cause i've had my hair always a bit longer and if i get it really short it will be quite a big difference and people will see the receding temples. (now it's not noticeable cause other hair kinda covers it)
I think it's a bit similar to Brady Quin's case:
