I'm either in front of a computer, sewing machine or the car. I do take breaks and often because of what computers can often affect the eyes. Cell phones just as bad. I fell a few decades ago leaving my apartment with my son. The steps were icy and I went down 6 icy steps on my tailbone. My bottom was definitely very sore. Had a doctor's appointment that next Monday for a yearly. My bottom was still sore. When my doctor saw my bottom he nearly passed out and his nurse did pass out. Sent me over for exrays and I had fracture my tailbone and hairline cracked my pelvis. Surgery could've left me paralyzed so of course I opted not on the surgery. Sat on a lot of pillows and every once in awhile I get a twinge if I try to get up sideways. My son was 5 so that was in "77". Scoliosis on top of that doesn't help. Amazing though I gave birth in "79" to an 8 lb. baby boy and not by C-section. I get up off my keester as much as I can and sometimes just more comfortable on it. The more I sit the wider my seat gets and that needs to stop.
