Iʼm a hiker.
Being a father makes me do a lot of things like playing football (soccer, if you like) or roundball with the kids. I also go to close (ie. within 10km) places by bike, both for environmental reasons and for the sake of exercising.
But my main thing, whenever i need fresh air and moving my body, i go up a hill. I usually go up, have some time alone on the top, thinking and planning and then making my mind go quiet, then come down. I almost never stay for a night, camping is reserved for the kids, too.
