I'd say the opposite about switching companies. If you want to make sure that you have no new ideas and increasing tunnel vision with regard to other aspects of life then stay in the same job for long periods of time doing the same thing with the same tools, day in day out. Have no outside interests and work long hours, putting your entire identity and energy into one company/task/organisation/product, and that's a good recipe for burnout. Also definitely don't exercise and always eat at your desk.
