This question popped up the other night at friends place when they where inquiring about booking in some lessons with me at their child's school and I pondered for a moment and begun to explain -
Music is technically a language, and by learning how to make your instrument 'speak' this language opens a part of the mind that will create a sense of wonder and eagerness to go further into the language. The guitar can become addictive in this way and since music is a form of self expression, people of all ages can relate. Just think for a moment, sometimes a piece of music touches us in a way that can lead to laughter or even tears, or just bring back memories of great or sad times...even past moments that had taken a backseat in your mind can be relived with the right song or even just a style of music.
Music can also alleviate stress, I can't tell you how many times I have been overthinking a problem and the guitar has help clear my mind. If I'm feeling down, a cheerful upbeat song can change my mood very quickly. If I'm feeling too serious about something unimportant, a silly song soon fixes that! Teenagers can benefit greatly from guitar, being a tough time for them feeling all sorts of mixed feeling like overly self conscious, stressed or just confused music can help build confidence and self esteem.
Pre-teens can benefit greatly from music also as it creates better learning capabilities, increased motor skills and improves creativity!
I have had older students of retirement age that have taken on guitar and they have expressed a feeling of joy making their own music and also a new thirst for knowledge!
So there are many benefits from learning to play the guitar and age is no barrier, I have taught students from 6 years old to 76 years old and all have progressed accordingly. So unless there a physical reasons why you cannot play, I truly believe anyone can learn guitar with enough determination and dedication and a good teacher. By the way there is a guy on YouTube with no arms who plays guitar quite well with his feet and toes....determination and dedication!
