Today's practice session was productive. I stood for 3 hours playing the guitar, the guitar was resting on my tummy (imagine yourself standing up playing the guitar and position how it will rest on your tummy). Dang, my tummy started to sweat alot because there was no space for wind to pass through and i think the mechanism started giving off heat from the back of the guitar. I swear it had the same effect of wearing the uZap from osim, the massaging belt which straps on your tummy and vibrates with a heater in it and making your tummy sweat. Cheeeeeb, i think i lost a number of kilos from playing my guitar namely the uGuitar.
