Like the idea, but don't think you're up to it?
For the last few years my husband, Steve, and I have been house-sitting around Australia, first by car and then by electric bike.
Now, before you say, 'Oh, I can't do that,' perhaps I should mention that we're both 50+, don't have a stash of money in the bank, and have never, ever, held a gym membership (or set foot in one as far as I can remember). So don't count yourself out too soon.
The life of a full-time house-sitter and Digital Nomad is a fun one... It's full of variation, activity and adventure, yet also more than enough time to just sit and watch the scenery - and, of course, here in Australia there's more than enough scenery to watch.
