I used to build snowmen with our without the family kids. I would fling myself backwards into the deepest snow banks for snow angels. These daze I just haven't the zip.
I also taught all the family kids until my grandson how to do summersaults and cartwheels, but again my body just won't. But to quote job in the Bible, can I accept the good from God but not the bad? I was nearly indestructible for 40+ years and did pretty good till 60. So my age and injury issues r just the other shoe.
