I grew up dedicating half my time out of school to watching sports and the other half to playing. Now it's really Arsenal.
At different stages, much of my time would go towards
Football - watching Juventus, Kaiserslautern, Rangers, Marseille as much as I could
Non-football - NBA (Lakers - particularly the Lake Show that preceded Shakobe), tennis, F1
Nowadays, it's really Arsenal, Arsenal, Arsenal, and then Champions League and Europa games involving Real, Borussia, PSG, Juve - all of which are significantly more enjoyable to watch than Wenger's footballing frankenstein.
