Are my arteries "springier" (say) -- more responsive, maybe even healthier -- if I'm 120/100 than if I'm 120/90? What are the limits -- how long would I have lasted at 60/40 (lying down)? Doesn't it depend on a balance between the pressure of the "pump" and the elasticity of the walls of the "pipes"? Don't they communicate and coordinate in other ways than pressure (hormones, ANS, electrolytes,...)? Do I have to jog, or will ERG do it? And how sensitively do that cuff and that dial indicate (resistance to) failure modes in such a system? (Modulo, perchance, the attendant's coefficient of sycophanticity.) -- --John Burge {the.world}!trwrb!logico!burge [818] 887-4950 LOGICON, Operating Systems Division, 6300 Variel #H, Woodland Hills, Ca 91367
