A part of me would love to try, as terrifying as the notion sounds but realistically I would not attempt it. Not just because of the obvious efforts involved in such a task but because I think my wife might have a thing or two to say about me leaving to spend a couple of years (or more) cycling around the world, while she stays at home raising our young children.
Also once they are older, I too will be even older, plus unless she is fed up with me by then (fingers crossed she isn’t), I rather doubt she will be much more keen on me going. I think if I was to do something like this I should have tried it back when I was in my twenties, not now that I am into my forties.
Oh well, I will leave it to the younger generation. Shame ðŸ˜„
