It would be useful for people to get out of the all-or-nothing mind-set that unless they exercise for 30 minutes, they're wasting their time.

It's a mind-set where we don't think we're old.

It is the sign of a dull mind to dwell upon the cares of the body, to prolong exercise, eating and drinking and other bodily functions. These things are best done by the way; all your attention must be given to the mind.

Problems are to the mind what exercise is to the muscles, they toughen and make strong

It is mind boggling to remain that consistent for that long of a period. Everyone is due for a let down, or injuries or bad breaks, anything could happen. To go that long is unbelievable.

A mind is a terrible thing to waste, and mine is shot.
