Will it and set to work briskly.
The most common objection that I hear to walking as exercise is that it's too easy that only sweaty strenuous activity offers real benefits. But there is abundant evidence that regular brisk walking is associated with better health including lower blood pressure better moods and improved cholesterol ratios.
I spend so much time with the brightest and most talented and well-rounded people. I've had the privilege of having long and very intellectual conversations with people and sometimes I just sit there and listen. It's like a better version of a class. Even though I'm not sitting at a desk and in school I'm still learning all the time.
