Texas city updating ambulances to haul heavier passengers.

Oink.

Medstar is converting its older Ford chassis to heavier Chevrolets, which cost $7,000 more but can carry an additional 800 pounds, said Matt Zavadsky, Medstar associate operations director.

"It's built to carry the extra weight and not be so saggy," he said.

Too bad humans are not designed to carry the extra weight and not be so saggy.
