Ask the master to explain the health of the old lady

Whether the old lady is healthy or not, we need to use scientific methods. As we get older, all the flatulence functions of the body have declined. There must be this disease and that, but if you have scientific maintenance methods, you can still live longer. Isn't there a scientific saying now? Live a long life despite illness. It is useless to be superstitious or listen to Feng Shui gossip, and it will be harmful to you.
