“I thought about evolutionary historians who argued that walking was a central part of what it meant to be human. Our two-legged motion was what first differentiated us from the apes. It freed our hands for tools and carried us onthe long marches out of Africa. As a species, we colonized the world on foot. Most of human history was created through contacts conducted at walking pace, even when some rode horses. I thought of the pilgrimages to Compostela in Spain; to Mecca; to the source of the Ganges; and of wandering dervishes, sadhus; and friars who approached God on foot. The Buddha meditated by walking and Wordsworth composed sonnets while striding beside the lakes.
Bruce Chatwin concluded from all this that we would think and live better and be closer to our purpose as humans if we moved continually on foot across the surface of the earth. I was not sure I was living or thinking any better.”
― Rory Stewart, The Places in Between
Our upright gait is not just a defining feature of what it means to be human. It also makes our bodies and brains work better.

5 surprising benefits of walking
August 25, 2022
The next time you have a check-up, don't be surprised if your doctor hands you a prescription to walk. Yes, this simple activity that you've been doing since you were about a year old is now being touted as "the closest thing we have to a wonder drug," in the words of Dr. Thomas Frieden, former director of the Centers for Disease Control and Prevention.
Of course, you probably know that any physical activity, including walking, is a boon to your overall health. But walking in particular comes with a host of benefits. Here's a list of five that may surprise you.
1. It counteracts the effects of weight-promoting genes. Harvard researchers looked at 32 obesity-promoting genes in over 12,000 people to determine how much these genes actually contribute to body weight. They then discovered that, among the study participants who walked briskly for about an hour a day, the effects of those genes were cut in half.
2. It helps tame a sweet tooth. A pair of studies from the University of Exeter found that a 15-minute walk can curb cravings for chocolate and even reduce the amount of chocolate you eat in stressful situations. And the latest research confirms that walking can reduce cravings and intake of a variety of sugary snacks.
3. It reduces the risk of developing breast cancer. Researchers already know that any kind of physical activity blunts the risk of breast cancer. But an American Cancer Society study that zeroed in on walking found that women who walked seven or more hours a week had a 14% lower risk of breast cancer than those who walked three hours or fewer per week. And walking provided this protection even for the women with breast cancer risk factors, such as being overweight or using supplemental hormones.
4. It eases joint pain. Several studies have found that walking reduces arthritis-related pain, and that walking five to six miles a week can even prevent arthritis from forming in the first place. Walking protects the joints — especially the knees and hips, which are most susceptible to osteoarthritis — by lubricating them and strengthening the muscles that support them.
5. It boosts immune function. Walking can help protect you during cold and flu season. A study of over 1,000 men and women found that those who walked at least 20 minutes a day, at least 5 days a week, had 43% fewer sick days than those who exercised once a week or less. And if they did get sick, it was for a shorter duration, and their symptoms were milder.
