Do you think that it is possible for a person to be too old to learn to play a guitar as an adult? Personally, I do not think that it is possible to be old for something such as learning to play the guitar or any other instrument. As long as you have enough determination and time, you should be able to learn to play woodwind & brasswind even if you are old. There are some instruments I would like to learn to play. One of them is the bass guitar for example.
