Rightly said. If we take care of them, we are indirectly motivating them to live longer. The age are not a burden, even with them been old we can benefit a lot from their wisdom as we care for them. As they grow old they become vulnerable. So like you mentioned, we need to look out for their mental health, hygiene, environmental safety and so on and so forth.
Our age parents and relatives are our responsibility, we should do that with love and joy. Thank you for sharing with us.i really enjoyed reading through your post.
Good luck with the contest.
