Time to start worrying?!

[jason2]

Hey everyone,
Just wondering, lately it seems like my hair is becoming a nightmare to style, and I seem to be receding alot around the temple areas, and I was wondering just how bad it is, and potentially could be! I'll be 29 in August, so I suppose a bit of receding is to be expected, but the past while it just seems to be getting really bad around the temples, and I'm stressing abit, will it stop or keep going?! My dad has a decent head of hair, and both my grandparents had good heads of hair.
My crown seems to be ok, so really just wondering what you guys think from the pictures... should I start getting my hair cut really short so its not as noticeable?
Thanks for looking, and giving me your thoughts!
