It's absurd, but he partly reflects on that himself: "But more than anything, it was therapeutic for me. Some mindless entertainment. I'm not a big TV watcher. It allowed me to detach from the realities and the pressures of life."
If its really relaxing to you, I rest my case. It wouldn't be to me, in same way no computer game or general computer activity ever could. Physical movement, ideally in the nature, the wilder the better. If you live too far reconsider permanently improving QoL by moving closer. Recharges batteries like nothing else.
There is still tomorrow to be more active, right, to catch up. But not with the same mindset that wasted today or yesterday.
