Learning to play a musical instrument is a great way to exercise and strengthen your brain. It has been proven that the critical development and problem solving centers of your brain are activated whilst learning or playing a musical instrument. That aside, there is no feeling like being able to play a musical instrument, no matter if you're just chilling on your guitar at home, impressing your pals on a piano in a bar or on stage as part of a band, playing a musical instrument is awesome!
