68 is too young to hang out at senior centers, where people consider themselves old. Really. If he lived in FL or other place where retired citizens congregate to live happy active lives, he'd just naturally become popular overnight with ladies who want to stay active and involved in life.
As a senior unwilling to act like one, I know this from personal experience. About five minutes after moving into a non-senior "gated community" in FL that had a clubhouse, pool, golf course, I had invitations to everything from everyone, met dozens of people within weeks, had a great deal of fun. And I'm a grrrrrl! Men have an even easier time.
I've been single for ages, lived all over the country. Believe me, those sunny places where you're outside much of the time present opportunities for meeting people that you just cannot imagine in snowy or rainy spots where people stay indoors. It just happens.
I'll pass on that advice to Dear Old Dad. And yes, he's a very "young" 68 to say the least. If I have to hear about his sex life one more time, I'll scream! He gets more than I do, and I'm a functional, sexy, 44 year old Soccer Mom, LOL!
We are leaving for a trip to PV, Mexico on the 20th. He is testing out warmer climes, and I wouldn't doubt that a move to the Sunny South isn't in his future.
