My wife and I are divers, my daughter is a competition swimmer.
I'm a Floridian so swimming/boating skills were a thing for me, the women in my life have all been divers so getting certified was a priority. The flip side is while I didn't love being "Airborne" while in the Army I did take to sky diving in a modest way, my wife and daughter have taken to it with a vengeance. In my old job civilians got to jump once a year with the resident Army and Navy cool guys and the invites went to my wife with a +1 (me) even though I worked 100" from their buildings.
In the end my wife and now 17yo daughter have no fear except for cold, but if you want to do anything fun their with you because their addicted to adrenaline.
