That rather rubbish mate. Just a couple days riding with me at GT then a big one on my home turf and you’re wasted. I’m taking that personally. 😉
Use your time in a way to benefit you further than to just take up the next three weeks.
As good as a puzzle, airfix and console games are they only serve as gap fillers, which the porn won’t even do.
Learning how to built a wheel or service a fork would be a more useful thing to learn or practice.
Are you allowed walks? You could do as i do, but in a small scale.
Pop out for a quiet wander through the countryside and soak up the air. Have a look about and open your eyes to what’s happening all around. Take photo’s write about it and share with the family how amazing and diverse life is.
Of course that’s my passion and i can’t expect everyone to find it interesting.
You could always get a train set or paint meaningless little diecast model of soldiers or warriors and paint them.
Get a little lathe and turn some wood, create something YOU made.
