“Moderate-intensity activity is something that you can do while … talking comfortably, but you cannot sing.”
~ I-Min Lee, MD

“The study has revealed some new discoveries … There are no drugs or gene discoveries that even come close to providing these kinds of health benefits.”
~ Paul Williams, MD

“I think it’s important for clinicians to recognize, however, that the risk appears to be greatest in habitually sedentary people who engage in unaccustomed vigorous physical activity.”
~ Barry Franklin, PhD

“If you intend to remain sedentary you should see your physician to see if you’re healthy enough to do so.”
~ David Swain, MD,
