Got healthy and realized how much I was missing

I was always the 'too tired' dad. Too tired to play in the yard, too tired to take the kids hiking, too tired for anything. Couple years ago I was like 80 pounds overweight and my knees were shot. Doctor said I was heading for a heart attack. That scared me straight. Lost the weight, started working out, cut out the junk. Now at 48 I can actually keep up with my kids. We run around the park together. I taught my son how to skateboard last week. I never would have had the energy before. I don't know who I was before but I like who I'm becoming.
