Can Tech Make us Healthier?

Can tech make us healthier? Sure, after it quits making us fatter and lazier. Researchers need to make up their minds about what tech is "doing" to us.

He pointed to a program--Cryptozoo--that his group created in partnership with the American Heart Association. The effort encouraged people to do various exercises in public places to unlock virtual "urban monsters."
