"It's in the attitude... and a healthy, clean lifestyle, of course. 🥰 Our minds and bodies are inextricably connected. I've found when I eat well and get enough rest and exercise, I have so much more access to that inner joy that makes life fun!"

The mathematician also shared a second tip for staying happy.

"The other secret to life? Taking all that gratitude and giving back to the world in as many ways as I can. My grandmother always said, 'The way to be happy is to make other people happy.' Spread it around...🤗❤🤗."

"So this is 46 ... no makeup, no filter, no hairbrush. 😅 Man, 45 was a rollercoaster. It's interesting having a birthday so close to Jan 1st because with each new year comes a new age," McKellar wrote then. "My year 45 ... taught me to weather storms in a way I'd never had to. (I think most of us have experienced that in the last year.)"
