I have often heard people say that once they retired, they didn't know how they ever found time to work. I think it's because, when we work our days are more structured so we are aware of time. Once we leave that structured life, time becomes less important.
Time is the same as always, just that body deterioration moves faster and faster until one day—poof, mind and body no more, unless there is a hereafter and the new me works in a kennel caring for wolves, dogs, and even ferrets, separately of course.
