My husband is seven years older than I am but I have three older brothers (and he, as eldest sibling has three younger brothers) so I can deal okay with the age difference until I start thinking about who's going to die first and looking for areas his age might be getting to him (he'll be 65 in August). My energy and health are changing as I age and I can imagine now, like I couldn't when I was younger, how that actually is/works.

My T once joked my husband was "much" younger than she is. I know she got her doctorate in 1971 and had her son around then. I wouldn't think she was more than 35 to have her son back then. If she was 35 in 1971, that would make her 72 this year.

I graduated with my BA in 1972. I know she did something other than school/psychology before getting her PhD though. Assuming it takes around 5-7 years to go through grad school and adding a year because in 71 I was still a year shy of my bachelor's, she was "at least" 6-8 years older than I am I figured. I think she's around 69 or so now; she retired 2 years ago and assuming she worked a couple years past 65. . .
