Looking for a job was rejected. How do you say you are old?

You want to ask how to find a job and be rejected when you are old? It can be said that I am old, and I have the advantage of being old. Work is more qualitative, and I won't wander like I did when I was young. Some things, being young may not have an advantage. Some jobs are for the elderly. Young people can't suffer. They live a life of reaching for clothes and full of food every day. I can't stand the storms of life at all. It's time for older people to show their strength. Still a good choice.
