Great article, Howie, thanks for sharing! I agree with Elaine; exercise is so important to get our blood flowing and reduce our risk of developing one of the communicable diseases (e.g. high blood pressure, type II diabetes, etc.).
The Canadian Society for Exercise Physiology (CSEP) has released physical activity guidelines for adults and children. I think what's important to remember is to incorporate exercise into your daily routine so that you're more likely to stick with it. For example, i'll sometimes walk to a washroom/water fountain on another floor to get in more steps!
Adults 18-64
