At 30, you have more than half your life ahead of you. At 40, you are just about the halfway mark. That's just the more serious longterm effects. The reversible short term ones are immediate. I was at a birthday hike for a friend - up a short granite hill for good views, some slow meandering around a lake. Very relaxed stuff. One of her guests couldn't make it up the hill. Full on bawling, had to leave early. This woman could not participate in even a casual hike for a friends party and she clearly wanted to be able to. I was fat but below the obesity level before I started my whole thing and the first "benefit" I noticed was that I could do any physical activity. I might be bad at it, but I could rock climb, and kayak, and play basketball with people. The "Oh, I can't do that" was simply _gone_.
