The limit seems to come down to how much food you can digest, rather than anything to do with your heart, lungs or muscles. It’s around 2.5 times your basal metabolic rate - the amount of energy your body uses while just chilling out. Researchers studying ultramarathon runners, arctic explorers and Tour de France bike racers have determined the maximum amount of energy a person can expend for a sustained period of time.

Critics say that Pfizer might have turned away from doing an expensive trial to confirm any benefit from Enbrel because the drug’s patent was soon to expire. Pfizer had evidence from insurance records that people treated with Enbrel were less likely to develop Alzheimer’s than were those who hadn’t taken the drug, according to a 2018 company document seen by The Washington Post. Some researchers are frustrated that Pfizer never published findings that hinted its rheumatoid arthritis drug, Enbrel, could have potential as a treatment for Alzheimer’s disease - and chose not to investigate the drug further itself.

Two cardiac studies at the National Cerebral and Cardiovascular Center in Suita were done without approval from an ethics review board.

At issue is the fact that fetal tissue is collected from elective abortions. “Today’s action ends a 30-year partnership with the NIH to use specially designed models that could be developed only through the use of fetal tissue to find a cure for HIV,” said UCSF chancellor Sam Hawgood in a statement. The government has already decided against renewing its contract with a lab at the University of California, San Francisco, that uses fetal tissue. The change could effectively end most fetal-tissue research in the United States. It will also require proposals from academic researchers seeking National Institutes of Health (NIH) funding for fetal-tissue studies to be reviewed by an ethics board. The US government is ending fetal-tissue research by scientists at its agencies.
