What was everyone else doing? Watching Netflix?
People pretend there’s no time but it’s all illusionary.
It's odd to suggest that people will have enough time to exercise if they just cut into their bedtime. Is the idea here that you sleep in the next morning, and then your wife wakes up earlier to take up your slack?
Is this your suggested solution for everyone? Increase your free time to exercise by reducing someone else's?
edit: No, I do it in the time I set aside to exercise.
This might seem foreign to you but to me it's no different from someone saying "I need £100 to pay the rent" and so they make time and find a way to pay the bills (usually a job). They don't "work in their free time", they structure their life around it because income is important to them.
I find that a lot of people say "I can't do that because X". I see it more as, well, I have to do that, so I can't do X, then.
As you say, scheduling time.
