 And when I was in chiropractic college, I was taught that normal blood pressure was 120 over 80. You know, with a range of 20, either higher or lower, making 140 over 100 or 100 over 60, the outer limits. You don't want to go over 140. You don't necessarily want to go under 100 as far as systolic pressure. Systolic pressure is when you have the lumbum.
