For those who have travelled so much and want more: congrats on being able to explore so much. I'm happy for you!
I haven't been able to travel for the last 18 years, and since I know I have a blood clotting disorder anything that requires more than a few hours of travel is off the table.
When I was a child I have been to France, Greece, Germany, Finland, Belgium and Great Britain. So I have at least seen some things.
But by now, France is already a stretch. But at least I can afford it.
My husband and I are set on going to Belgium, France and Germany the next few years (in that order). He promised me Paris, because that's my main dream as I have never been there, and I promised him Berlin but he wants to wait with that for a while.
