Hi,
I miss "None" in that poll. I was robbed and injured in Zimbabwe. In Oman a car crashed into my bike. I cycled in Haiti. Was uncooled in Chile. Nothing of that scars me.
I didn't made a long tour (> 1 year). May be I will do once - but I don't know. I'm not frightened to find a job afterwards, but after years of freedom I don't want to work anymore for my daily living.
