Thanks for all the good input. All the ideas and advice are valid for people here. For me, it is essential to have sufficient $ and good health at old age to keep on having fun. Having a MPA, who is of legit, semi legit or holistic nature to visit a senior at his home is not difficult. The main reason for a legit MPA not to make a home visit is security concern. However, if she knows you for a while and you are at 70-80s, she would not feel any threat. Probably, paying a fee similar to what we pay at her spa would be acceptable if we have the massage at a time when she is off duty.
I agree that we should keep active after retirement. One of my idea is to be a shareholder of a spa. Normally a girl would not like to partner with a guy unless the guy can contribute besides the starting fund. I have the idea of becoming a landlord of a small retail outlet and rent it out to a spa. The condition to give a special low rent is to allow me to have a small amount of share in the spa. I would help out in test drive when someone comes for a job. Ha Ha. The idea is not so much to make money, but to have something to do and of course some fun.
I would have a naughty girl to visit me once or twice a month to assist me in bathing. I heard there are free services provide by the Government/charity to help senior who has difficult in taking a bath by himself. When I looked at the helper's list on a charity organization, I found most of them were female. So, is it a good chance that a lady would be sent to help a senior for shower?
To enjoy a good life at old age, let's plan a bit far ahead!
