This time it is for plugging a podcast he recorded with fitness writer Ben Greenfield. Greenfield has espoused anti-vaccination views on Twitter and other platforms, continuing to do so despite measles outbreaks in the United States. > Dorsey retweeted Greenfield’s tweet about their podcast interview, commenting “Great conversation, and appreciate all you do to simplify the mountain of research focused on increasing one’s healthspan.”
