Is 21 too old to rush?

[LieutenantDan95]

I'll be an incoming junior transfer student at the University of Alabama next Fall and I'm 21 years old. There was no Greek life at my last college so I want to take the opportunity to join a fraternity now that I can. I don't want to look back and regret not joining a frat and I know I won't ever look back and regret joining one. But would it be weird rushing at 21 years old? I know most guys who rush are typically freshman (18 y/o guys) so I'm just not sure if my age would hinder my chance of getting any bids. Or maybe it doesn't matter?
