About the Author

Written by a Doctor Who Practices What He Teaches

I'm Dr. Scott McDonald — a healthcare professional with over 37 years of clinical experience and a lifelong student of what it takes to thrive in the second half of life. After four decades of watching patients navigate aging, I noticed something the research now confirms: the people who age well aren't lucky — they're intentional.

I created the Longevity Series to bridge the gap between cutting-edge science and the people who need it most. At 62, I'm not just writing about these practices — I'm doing them every single day.

"The goal isn't to live forever. It's to live fully — for as long as possible."
