I'm accident prone like you! On my last solo trip in Prague, I fell over twice in the space of 24 hours - on the same knee! In Tallinn, I pulled my quad muscle in my right leg climbing the city walls. I couldn't walk the next day and i had to fly to St Peterburg via Riga. Those plane stairs were a killer but people helped me. I was too proud to ask for a wheelchair - I was travelling alone. I was 69 going on 70. But I'm not going to stay home.
