I used to play Table tennis at lunch time in a few places where
I once worked and when I retired I joined a Seniors Citizens group that had a TT group which I became a part of and I also at the same time joined a Keenagers group that had Table Tennis on the agenda.
And participated in that for a number of years.
I have now been a member of a Men`s Gym at the local Health Clinic 3 doors away from my home for the past couple of years.
Not only my body benefits from these exercises but so do my eyes
If you know what I mean ,wink ,wink,nudge ,nudge ,say no more ?
let the reader use discernment .
