I agree. Potato chips and a workout is better than nothing.
Also, for old people and others with painful feet, crosswalks can really suck. One who drives to the gym and then uses a treadmill gets to control their speed during the physical activity. The car can go fast enough to keep up with traffic without stressing the person’s body.
I did zen training involving koans. At an abstract level, koans are a practice of trying repeatedly in the face of thousands of failures, without getting impatient. It’s the mental equivalent of Lucy’s punch-through-the-sign training in Kill Bill.
Try try try ten thousand years nonstop. That’s the mindset it takes to make progress with koans, and in the process break some of the mind’s longest-held assumptions.
Ever since I spent some years doing that, I love extremely hard video games. I don’t mind trying dozens or hundreds of times before I pass a level.
