Let's keep bed sores from killing the next one.
Driving down the highway today I started wondering why truckers never get bed sores on their butt. The answer of course is because they keep shifting position. From there it was a small leap to Superman, a.k.a. Christopher Reeves, and his recent death as a result from complications arising from bed sores. It seems to me with all of our technology it shouldn't be too hard to create a thick, weight-sensing mat that could sense where the most weight was currently being applied against it and gently shift the body to put that weight on other spots every hour or so to keep bed sores from forming. A carseat type mat would also be a helpful invention, along the same lines for use in wheelchairs.
These devices would quickly pay for themselves when used on paralyzed patients. Nursing homes would have lower labor costs because they wouldn't have to manually turn patients as often, and insurance costs would go down as the number of deaths by bed sore decreased (fewer lawsuits).
Speaking of money, rich folks wouldn't be satisfied with a common mat though, so we could create half of a sarcophagus to cradle them and shift them over a greater side-to-side and front-to-back range.
