Retired people are to be cared by their sons as well as by themselvesParents should be taken care of by their sons once they are retired from service. Besides this, the retired people also must take care of themselves.
I have seen some retired people, especially male members, moving around in the house with dirty banians and dhothis as if nobody was providing them a good dress. My father used to be like that only. I bought a washing machine and told him to put his dresses daily into that for my wife to wash them and keep them ready for the next day. He agreed to that and followed it till his last breath.
Retired persons should enjoy their retired life by wearing what they like, eating as they please, if health permits, and moving around. If their health is normal they should not hesitate to go to nearby temples and places, preferably with their wife. It is the duty of their children to take them to nearby temples or other places of worship occasionally at least, if not regularly.
