Marrying younger women (5-10 years younger) is common in more traditional societies for a myriad of reasons. I like it but that's just me. My folks were HS sweethearts and stayed faithfully married for 50 years till my dad died. It can work either way but yes at your age, I would look for a somewhat younger woman....early 30s would be fine..if you're 37. That'll give you plenty of time to "work on it".
Good Luck!
