I'm in a job now where I am stuck in a chair for eight hours. I wish I could go for a walk. Even my other non-work activities after suffered because I am mentally numb at the end of the day. My health is noticeably poorer. I used to go to the time gym a few times a week but as I got older gym life always is like a 20-something bar dating scene it felt alien and annoying to me. I have gone for a few bike rides on the weekends and that alone has helped I can feel it. But overall I'm am not even maintaining my health over the year. Summertime I can be active outside and weekends but the winter is the worst for no activity and more calories.
