Strength in Numbers

as in...the number of times my sister walked with her forced pal, "Herbert" (her walking tower of medicine/IV bag) around her hospital floor. One day it was eleven times. Yesterday she reported she was still feeling great and that she worked out on the elliptical and lifted weights! HUH? Didn't she just finish her first round of chemo on Saturday? Um...yep... That's my sister. Short (as in like 5 feet tall) and stronger  than most people twice her size!!
