BTW moving house, changing careers or controlling the transport environment around you are not easy things. Also good luck with "compensating" for pollution or sedentary working.
Nothing is "easy" which is why we're where we are with health and obesity crises.
"Compensating for sedentary working" is actually the simplest of things to do...
Get a standing desk
Walk around the office more
Take the stairs instead of the lift
Park further away
Have a lunchtime walk
Exercise in the evenings or at least at the weekend
But even the bigger issues, you "chose" where to live, you "chose" where to work, etc - these things are changeable in the longer term and lots of people do move where they live and where they work over time. No, it may not be "easy", but living a life in later years with health issues won't be easy either.
I had a sedentary job and weight rose to 24 stone, barely able to move, just shuffling from home to car to work and back. I gave up the job and got a local one, massive pay cut, but I saved a fortune on commuting costs, gained 2 hours per day and started being more active. That then led to me giving it up and setting up my own business a few years later. Again, not easy, in fact, very hard, especially losing my wage and living on credit card debt for a year until it started making profits. But it meant I could work a mile from home in a rented office that I could walk to. When in the office, I can work at a standing desk. I can also have a walk around the village/canal every lunchtime. No, it wasn't easy to get there, it cost me massively financially, when I started up, I had to work stupidly long hours so missed a lot of our son's growing up. The risks are huge. But, now, I'm fitter, healthy, half my weight, better attitude/control of food, reversed T2 diabetes, and feel fitter and healthier now I'm 60 than I was as a teenager.
As I say, the big things aren't easy, but that doesn't mean you have to accept facing the rest of your life potentially unhealthy, and ultimately with a shortened and possibly disabled old age.
