I have often thought if a person can live a normal life with only one kidney...... how can these people who see us suffer day in and day out still be walking around with 2 kidneys? How can a nephrologist watch a child suffer and die and not be tested? I don't know. At least if they gave one kidney and it was gone then they could not give again and they would have tried. But all the techs and nephrologists I know have 2 fully functioning kidneys.
Maybe they know something we don't.
Maybe they can't be down for 3 weeks?
