As long as you are living, you are capable to learn…
When I was still teaching drums about 15 years ago, I had a student who was older than me and he asked the question, will I still be able to learn to play the drums?
My answer was; as long as you are still breathing, you have the opportunity to learn, so it is up to you if you will learn.
If you are thinking of learning something new, don’t let your age, your condition, or somebody else be the reason why you won’t proceed.
Life is great because we always have the opportunity to grow. Learn all you can while you are able.
