"You can read all the dating books you want, but getting in shape is the only thing that works."

I don't know my guy. I'm 39, weigh 280lbs at 5'9 but am married to a smart and beautiful women a decade younger than me and 150lbs lighter than me. It's not a sugar daddy thing either, she makes more than I do. Not everyone is shallow and a great sense of humor / shared interests / good personality is more than enough for plenty of people. That said, being fit certainly ups the odds in your favor.
