Some interests: sailing, swimming (7 days a week - fitness is important to me - looking for same), art/culture, politics, making/fixing (my air conditioner comes to mind) things. I also have several old fashioned "hobbies" like collecting antique mechanical devices. My hand made t-shirts were included in the Emmy Awards presenter gift bags.
I'll defer to the local norms and list my occupation. Managing Director in investment strategy but I don't expect our relationship to have much to do with work (mine or yours).
