I was once like you. Old age is something one cannot dodge, old people had passed through your present pretty age before.
Pray that you may grow old with all your body parts. Some get old and get blind, others turn deaf or both. Several get their legs amputated with some health complications.
Many of the old are infested with multiple diseases, making life unbearable. This is where your services are needed. Don’t shun the company of the old people, it is natural, and you will definitely get there too.
