Both activities aim for technique and reliability improvement, both can keep you occupied by analyzing/planning between the sessions, both are directly dependent on your performance, both affects an item at a distance (kind of triggering similar feelings of control), both are (mechanical and fluid dynamics) hi-tech, both can be done outdoors as well as indoors and both can make you sweat.
