One of my daughters - now a cop in a Western city - was a paramedic in Yonkers. She always said that they heavier they were; the higher up they lived.
But I think her biggest whale was a 600 pound guy, and they were actually able to get about 6 firemen to carry him down the stairs from the 5th floor, not an easy feat, since these buildings have narrow stairwells and not much landing.
The family had kept the guy fattened up by bringing him buckets of fried chicken and pies when he was unable to get out of bed anymore. I wasn’t sure how he managed to go to the bathroom, but maybe I don’t want to know...
A diaper and someone in the medical field willing to roll him this way and that to change him and get a new one on him.
That’s how we do it in the ER.
