You don’t have to stop maximizing income in order to get fit and healthy. I schedule time to work out in my calendar. My wife and I prioritize workouts as necessary time. You can eat at a restaurant and order healthy options and drink water.
People who blame their work for being unhealthy are making excuses. I’ve worked 60 - 70 hours a week for 2 decades and I’m in excellent physical condition.
The problem is that top-level competitive work takes a lot of mental and emotional effort. So even if I’m spending time on health, I can’t do it work 100% effort, and so result is still suboptimal.
I have trained myself to shut off work when I stop working. This took a lot of time. Very rarely nowadays is my sleep or time outside work disturbed by what is happening at work. It’s a meditative practice, but once you really get in the mindset of work being for work, family for family, sleep for sleep, etc. then you stop being bothered.
You answered your own question? It sound like everyone else was sleeping.
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?
You don't exercise in your free time, just like you don't work in your free time.
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'm fitter (can run further, lift more, more aesthetic figure) than I was in my late teens / early twenties and it was all down to one decision -
I stopped prioritising maximum income and started prioritising fitness and diet.
Not everyone wants to do that, and with pre existing health and lifestyle choices it can be much more challenging for some than for others.
But it's there as a choice, it's possible, and it's a hell of a lot easier than it seems once you start to see the results.
