Miss my old body but love my new life
So I'm 40 now, got three kids, and my body is just not what it was at 28 when I was doing CrossFit every day and had abs. I'm 30 pounds heavier, way less flexible, sleep is a luxury. But honestly? I don't think I'd go back. I miss that version of myself sometimes, miss the identity of being that fit guy, but having kids gave me so much more meaning. I'm teaching my kids about health and fitness instead of just being fit for vanity. I'm still trying to get back in better shape but it's a different motivation now.
Missing the old body but loving the new life is the real trade-off. At least you know what you gained in the deal.
