I know Ma walks and does sit ups (yes, she can manage up to 20 sit-ups at one go) everyday, but I am truly surprised that she has been playing with the monkey bar!!!! She loves hanging on the monkey bar and let her entire body stretch, and gives herself a few swings. She always feels great after her swings and at 70 she looks great, very lean and trim and most importantly very healthy and independent. Best of all, she does not have a single strand of white hair!
