Getting in your exercise doesn't have to be going to the gym, running, swimming, etc. It can be anything that gets your heart and breathing rate up In this blog I discuss how much exercise is recommended, the value of different activities and what counts as exercise. drscottlear.com/2025/10/01/w...

No matter how good someone is at something now, they started from a point of not being good at the beginning.

What does being healthy mean to you? Is it how you feel, having no diseases, your weight? drscottlear.com/2025/06/04/w...
