I don’t need another hour right now, but most of my life if I had had the extra hour it probably would have been exercising. That’s what I skip when I am harried and don’t have enough hours in the day.
It’s difficult for me to go without sleep, so I usually get enough in, except when I was younger it would have helped immensely if the extra hour made school start an hour later. Schoolage was practically bordering on torture regarding lack of sleep when I needed it.
