Browsing my rather expansive, though only circulation standard (mostly), coin and banknote collection. Largely from the UK and her overseas territories, though I often have remnants from countries I've visited, or ones which no longer exist.
Also, sometimes whilst I'm playing RS, I practice my fencing, if I'm in a large enough room. Usually, it's just going through the motions, but sometimes I set up a dummy and put paper targets on him, and try to hit the targets. (I.e. Improve my accuracy when hitting).
I was once using a proper rapier (as opposed to my usual flexible foil or epee) and nearly sliced my laptop screen with the blade. I was trying to get used to performing a salute and when I whipped the blade sideways, I caught the edge of my laptop. Not my smartest move.
Needless to say, I stopped using actual pointy blades for practising, decided it's a little too dangerous.
If you only do what you can do, you will never be more than you are now.
When I'm not playing RS, I'm drinking Tequila, watching drifting videos on youtube/insta, attempting to save money for more parts on my car. Drinking with buddies talking about cars.
I like to read. My daughter and son in law talked me into a kindle. So I use it a lot now although prefer actual real books still lol. I also like to knit. I'm currently making scarves for my niece and nephew in the colors they asked for.
While playing though I keep caught up on my favorite TV shows. I have no television service. So it's been websites and netflix for the last 10 years or so. I keep Runescape on one half of my laptop and whatever show on the other. But generally reading when not playing lol.
