I actually learned that the hard way, failing to notice how much my svelte young bride's mother weighed and how she treated her husband.Always check out the moms skills and looks when dating the daughter. Just sayin’. Didn’t work for me tho as Mr Subs dad had beautiful thick white hair when he was older and well, he didn't get those genes I guess…
Genetics are a crapshoot as well. There are baldness genes in both sides of my family, but I have dense unruly hair like one of my great grandfathers. My first wife's family had baldness genes as well, but both of my kids have dense hair like me, and my build, though neither got my green eyes.
