An excellent physical activity, but also a healthy and uplifting mental activity. I just finished up drumming for about 30 or 40 minutes. Feelin' snug and cozy as I wind down for the night. As somebody who's been diagnosed with a list of conditions, music soothes my spirit. "Bilateral stimulation" just means both sides of your brain are activating simultaneously. Your system can hopefully start creating more dopamine and serotonin after enough musical activity and involvement.

Also, as a side subject, what kind of kit/set do you own? I have a 6 piece Tama Imperialstar. 10 inch and 12 inch rack toms. 14 inch and 16 inch floor toms. 22 inch bass. Sabian AAX cymbals, 21 inch ride, 16 inch and 18 inch crashes. Remo heads.
