Science superstar Stephen Hawking is taking a break from solving the mysteries of the universe to address the obesity crisis plaguing some parts of the world.

In a public service announcement, Hawking notes that too many people are dying from health related problems associated with obesity.

“We eat too much and move too little,” Hawking said in the ad for the non-profit Swedish health organization GEN-PEP.

Physical inactivity is the fourth leading cause of death globally, according to the World Health Organization.

Hawking notes that it’s time to change that.

“Fortunately the solution is simple: More physical activity and change in diet,” Hawking said, adding, “It’s not rocket science.”

Hawking, who was was diagnosed with a motor neuron disease when he was 21, and has been confined to a wheelchair for decades said he can’t understand why people don’t want to move.

“For what’s worth how being sedentary has become a major health problem is beyond my understanding,” Hawking said.
