Despite his graying hair, Bill Nye has looked the same for decades.

“I have really gray hair, and when I look in the mirror I can tell a difference,” the 61-year-old science guy told Page Six at The Paley Center for Media’s premiere of Netflix’s “Bill Nye Saves the World” on Tuesday.

When asked if there was a scientific tip to looking young, he responded, “I have to say, my ancestors were French and a lot of them eat really rich food, but they don’t eat very much of it.”

He added, “Despite my best efforts, I’m going to die. So I’m doing my best here, but just keep it in mind, you get 30,000 days if you play it really well.”

Nye’s new series includes panels, monologues and, of course, science experiments. Each 30-minute episode will tackle topics like climate change, vaccinations and alternative medicine.

“We’re in an unusual situation where our lawmakers are often ignoring signs and that’s inappropriate,” he told us, “First of all, the economic affect of science is very important. Innovation is what keeps a country competitive on the world stage. If the United States were to stop innovating it would fall behind very quickly.”

He added, “We just want to remind everybody that although science is not partisan, it is political. Our system of laws, which is what creates the country, is based on science.”

The show, which premieres on April 21, also stars science YouTuber Derek Muller and comedian Joanna Hausmann. His PBS show “Bill Nye the Science Guy” aired from 1993-1998.
