Returning to the question of change as I get older, it is a challenge. I understand that I am more invisible to young people, but try to accept that. I am letting my grey hair grow in after so many years of covering it and am surprisingly enjoying it. I lost 40 pounds and can now move easier on my replaced hips and knees. The best decision I ever made was to fix those worn out parts. After so many years of pain and limitations, I am now free to take daily long walks (my only exercise now). I have to limit what I do on our property as bending over hurts my back, so just have to ignore the pesty weeds. Anyway it will soon be too hot to spend much time outdoors as I don't function well in the southern heat and humidity. I just hope I can stay as well as I am at 75 and for now just take one day at a time.
