My first guitar was TRASH and had about 1/2" of action, and I put 60 gauge sets on there and played like six hours a day. My callouses are still invincible to this day, I can play a three-hour set and never even feel it. For wusses, I advise finding a guitar with low action and using light strings. For anybody I respect, it's the opposite.
Steak, eggs, potatoes - fruits, nuts, berries and forage. Coconut milk and potent herbs and spices. Tea instead of coffee now and teeny amounts of kelp daily. Let's see how this does! Not really had dairy much, and gut seems better for it.
