I spend a lot of time researching travel destinations and how to get from the airport, how to use the local transport, choosing a good spot to stay in, that kind of thing. Mind you I rarely get to go to all these places in the end! But armchair travel is great.
I can potter around the garden for hours too. Not much achieved as I can't move the big bags of compost or the heavy pots without help lol. Then I plant things, don't like the look or the siting, and pull them up to start again. Then I leave it for the day. Or two days or more till I get in the mood again.
I walk lots, just around my local area which has a river, lots of nice parks and a few independent shops together with a big shopping centre, and my favourite, great little coffee shops. I head out, and either call in to the shops, or stop for coffee, and then say feck it, and get the bus back ha ha.
Other than that I read and like many others have the guilty pleasure of watching crime stories and watching YouTube and down that rabbit hole I go. Audiobooks are brilliant for the lazy reader like me too. I'm retired and can do whatever I want now, which is often very little, but after a lifetime of working, who cares!
