Actually, medicine is keeping us alive longer. some modern food is shortening our lifespan, yet some of it is actually beneficial to us. Depends on the habits that your talking about, like sitting at home with electronics and eating a bag of chips, yea that’s crappy. But other modern hobbies like sculpture/art, new technology, is helping us become better humans. Though some people can’t seem to adapt to new technology, and they are the people holding back mankind from evolving.
