Like his friend Neil deGrasse Tyson, Bill Nye isn’t big on New Year’s resolutions.

“The changes I want to make are generally part of a process rather than a sudden shift or toggle to a new position,” the “Science Guy” told The Huffington Post in an email. “With that said, I have some goals for the new year.”

One goal is to finish his next book.

“It’s about climate change and how we can become the Next Greatest Generation,” Nye said in the email. “We can get to work the way people did during World War II.”

Another of Nye’s goals for 2015, believe it or not, is to pick up trash with his left hand.

Why would Nye want to do that? In order to “preserve the nominal cleanliness” of his right (dominant) hand, he said, adding, “No kidding.”

As Nye went on to explain, “The left hand will encounter a good deal more germs and filth. The practice is both to reduce my chance of getting infected and to reduce the chance of my infecting people I meet. It’s both out of self-preservation and respect for others. Writ large, it may be an evolutionary urge to protect one’s own health and the health of the tribe.”

Hmm. When it comes to thinking scientifically, you gotta hand it to Nye.
