In modern American society, one need not leave their cozy home until the undertaker arrives. Almost everything, from toilet paper to vehicles can be purchased online and delivered to your door. Food and booze are just a text or phone call away.
For the more adventurous, sight-seeing from the car can be enjoyable, especially since fast food drive-thrus are widely available. Here in Denver (and I assume in most big cities), one can now get their oil changed while staying in the car. During my recent visit to the massive confines of DFW, I learned that one need not walk to the burger joint for nourishment; rather, the food can be ordered by text and delivered to your gate. The only reason to get up is to heed the call of nature or to get on the plane. Of course, massively obese persons get the best deal: a ride through the terminal and early boarding with other disabled individuals.
Staying active is the best way to combat the degenerative changes of aging. Though commendable, one need not be an elderly triathlete or a pickle ball champion to obtain the benefits. A daily walk is sufficient for most of us.
