My new focus is raising my 2 and 4 year old kids. I get to share things I've learned, and pass on some of my favourite things from my childhood - just last night we taped my oldest's new hockey stick (hot pink and Superman hockey tape was used), and watched the animated Transformers Movie from 1986.
Other than that work is always angling me to volunteer my time to doing things with the Regiment. Currently I am helping groom Junior Officers to become future Infantry Platoon Commanders. Sort of like raising my own kids too - only these ones I don't have to literally wipe the asses of.
EDIT: I should add that I also expend a lot of effort in strength training (work kind of demands it) - pun intended. For example I am routinely around a 1.4:1 power to weight ratio for my bench press (because gym bro metrics) at 5'-11", 168lbs and 9% BF; and my last fitness test put me in the top 2.2% nationally for my age/gender split for the Canadian Armed Forces as a whole (only reason I didn't score higher was because of the flu).
There. I got to brag. Publicly.
