Yes. We have a mini set up that I put on an outdoor table and play every now and then. It's a fun sport, good exercise, and even my kids are surprisingly good at it (on account of their being only 5 and 7), so it's good fun!
My father was on a professional table tennis team, so it's in the genes! Table tennis is addictive - such a great game and you have to keep moving constantly. Anyone can play, and it's really good for sharpening your reaction times.
Yes.. I love the game, the various styles we can play in. I have been playing Table Tennis on & off since my schooling years and feel its a good exercise for mind and motor skills. However, just while typing this line flexed my wrists and found that they're a little stiff, so playing TT again with my old proficiency is going to take some time.
