Tell people you spend 12 hours a day starring at a screen and they won't bat an eye, tell them you walk 10k step a day and they'll try to convince your it's unpractical, unhealthy, "10k is a made up number anyways", "I don't have time", "isn't it too hard?"
i want to spend my free time with my kids, not walking somewhere in the woods/city.
i walk 2 hours once a week after their bed time. but i certainly can't do that every day or i would die of exhaustion.
