You always get some one ignorant enough to put a spanner into some one's happiness. They are no harming any one. The complainer should join them and also have the benefits a good healthy life. Some times people think they know too much and never listen's to others, it's their bad luck. Listen every one if you don't fancy it you don't have to do it. I am 74 my wife and I only started doing YOGA since last 8 years . I feel like a young man again. I coul'd believe our vaining sexual life restarted. Laughter is the best medicine, one must laugh every day. If anybody is suspicious I am too glad to answer their enquiries. Life is too short, don't make it shorter still by not doing any YOGA or other exercises. Only one life we have got. Once gone you are gone for good. While here enjoy it.
