Definitely more challenging to handle as we age. The good news is you recognize this and aren't ignoring it. Even if it is a difficult realization and problem to confront. You are a smart and passionate dude though...you'll right the ship. Just takes a bit of effort and commitment. After the holidays I am doing the same regarding my diet. Going to start yoga as well for my back and really give a tremendous go at taking a bit better care of myself. No more of this...
