I was thinking about this a while back: Physics and math are sort of my forte, and it's actually quite interesting how you can see that on my ancestors. My father studied uni.-level math, and his father is sort of a know-it-all guy: He can construct and build all sorts of things (not only did he build my grandparents' home, he built a water purifier and all sorts of gizmos to go with it). My aunt is an architect, and my grandfather on my mothers' side was a carpenter, but like on my fathers' side, he also built all sorts of things.
How about you? How do you compare to your ancestors?
