I'm lucky. My spouse only looks better with every year that passes.
I have consistently looked the same through my whole life. DeauxDeaux has some weight on her but my mom has a bad thyroid. My father's mother was a carbon copy of Sophia from Golden Girls. I've heard from guys that the wife looks like mom 99% of the time hehe!
I am also fortunate that way. But my wife works at it -- 2 hours of exercise every day, plus flamenco dance classes about 8-10 hours a week!
I, on the other hand, have to run 1/2 each day just to hold the line. My wife has a good visual filter to see me every day.
