Yeah, just like vampires. But they sure seem to live a long time...and it seems (seems) relatively rare to see diminished mental capacity in many leftie icons.
When they miss a transfusion, do they trip off curbs into scoobyvans? Bang their heads in airplanes? Trip backwards up the stairs? Should carry an IV bag around of the stuff /s
They don’t live any longer than a lot of ‘good’ people do; and being actively interested in something in life, having a vital mission that you care about, helps to keep you young and clear-minded.
Look up Jacques Barzun, who lived to be 104, and published what many believe is his greatest work when he was 93.
