A recent Dice Tower video had the three guys give their top ten (non board-gaming) hobbies and I started thinking about how hard I'd find it to make a similar listing. With effort this is the list I managed, the four at the end are on the list to make the list 10, and everything is in order for how I feel right now.
Reading - Before I started having 24/7 access to the internet I was reading many books a year, 250 at peak. As a teen at high school I usually read assigned reading far ahead of the others in the class. One of the books was such that I actually read the four sequels before some of the others had read the first. The reading I was doing at the turn of the century was also impetus for the amount of books I purchased, usually on the cheap. A collection that's at 860 books right now if you discount the few audiobooks I have digital copies of. I did stop buying any significant number a few years back now, largely as I realised that I wasn't going to read many if I purchased them.
TV/Movie Watching - My collection of DVDs is up to 234 at the moment, 101 are movies, the other 233 are TV shows with each season counted individually. There are almost none that I've not yet watched, mainly because I haven't got the entire series run of the TV show.
Video Games - While on my own without internet this was the other big time sink besides books. I have played many hours of StarCraft, Dune, Command & Conquer (and Red Alert), Heroes of Might and Magic (I - IV), WarBreeds, and some other games. Since getting Steam a few years back I've played a number of other games, apparently spending about 847 hours on the games I own there, which doesn't count those that were available as demos.
10 Pin Bowling - One of the very few things I've made an effort to do over the past 15 years that would cost money to do on a regular basis. I remember scoring better than 100 in most of the games I've played but haven't done much better than 120. For whatever reason I have also done okay when bowling left handed, not quite reaching 100 as a score on most of the few times I tried.
Logic Puzzles - Something I seem to get from my father, the need to reason out what the clues indicate and cross reference the information makes the type I linked more appealing than Sudoku. Kakuro puzzles also appealed a lot more when I found them. During one of the church camps I had a book of puzzles that I spent a lot of time working on, when I couldn't get board games going. It's also the second best thing to be doing at work during downtime if I don't have a book with me.
Archery - Most of the church camps I went to over the past decade had something set up for archery and I took the chance to have a go at each of them. Without a lot of practice I won't be improving but I seem to manage well enough most of the time. And for whatever reason I seem almost as good with my off hand.
Child Minding - Not something I really consider a hobby, but one of the DT guys had youth group on his list. For a large portion of the time I've attended church services I've spent much of that helping with the Children's church portions of the services. A couple of years after shifting into this flat I was asked if I'd like to help with the Mainly Music sessions that were being run at the time. For about five years I was spending most of my Wednesday mornings during term times helping there, dealing with CD and OHP to start and then often getting climbed on. I also had a year or two where I was helping out at another thing where I'd be in charge of two or three little children while parents discussed things.
Mini Golf - Much less walking than proper golf, and more interesting scenery a lot of the time. Not something I'd do a great deal, even if I had the money, and going back to the same course time after time would likely bore me.
Making Lists - Not something I'd have considered if it wasn't on one of the three lists. I spend a fair amount of time makings lists of things, although mostly it's Board Games related. For example; I've been tracking what I play for the past decade which leads to Five & Dime lists at year end. I also have listings of all my books, DVDs, CDs, etc. that I started more than 20 years ago (for the books anyway, DVDs were from about 13 years ago). I even have a lists tag for these entries.
Snooker, Pool, whatever - The appeal of this for me is bound to be a matter of math. Work out where to hit the ball to get another in a hole. I don't do all that well especially when first playing but it's still enjoyable.
Board Games - would have been first (by a large margin) but it's disallowed because it was specifically things other than board games that they were listing.
Edit: I should have spent more time thinking about this before posting it.
Rock Climbing - Another thing I've done when given the opportunity at church camps, and which I did quite well at while in High School on the rare occasions we got to do it then. I also went to "The Roxx Climbing Centre" once or twice, a decade or so back. (Should have been in the first grouping.)
Crossstitch - Not something I've done since my teens, the last was in my first year at Polytech. I still have the patterns, and the made up kits, but I've not got any closer to doing more even with patterns and thread etc.
Model Making - Not something I've done since my early teens at the absolute latest. I occasionally made Airfix type models and probably had close to a dozen all up before my parents shifted at the turn of the century. I remember purchasing an Aircraft Carrier model near the end of the century that had problems in what was included. That would have been the last I made if I had actually tried to muddle through.
