Physician Urges Standing To Lengthen Life

What does this say about people who use wheelchairs? 

[From article]
A leading UK sports consultant has said that the public should be encouraged to do more “low-level” exercise and that standing up for three hours a day can extend life span by two years.
Dr Mike Loosemore, head of the Institute of Sport Exercise and Health at University College London, said: “There is now enormous evidence that simply standing makes huge differences to your health.”
“Low-level activity, even regularly getting off your seat, can change your life forever,” said Dr Loosemore, writing for the BBC. “Active individuals reduce their risk of heart disease by 40% against their inactive counterparts.”
