Darts

So, it turns out darts is actually quite hard work. You have to stand up for a long time, walk to and from the dart board to collect your darts. That's over 4.5 metres of walking for every throw. Plus you have to actually throw the darts. And rearrange the entire house to find somewhere to put the dartboard. And drill holes in the wall.

I think I'm going to develop sitting down darts. It'll catch on very quickly. And some kind of sticky tape dart board fastening.
