haha actually got a lot of uncle and aunty play pickleball! I think it's great for them. They can stay active. Keep their coordination and movement so can stay healthy. If stay at home do nothing / watch tv, I think deteriorate like get all those Alzheimer's and other health issues.
I actually would prefer not to sweat so much ahha. sweat a bit ok but cuz malaysia so wet wet humid then no choice ;( unless go 91 where they blast AC and play
