You cannot get blood from a turnip theory of travel.
I do not worry about being robbed when walking on the other side of the planet. The reason is simple, even if they robbed me; they would not get that much. I only carry enough money in my pocket for today.
In Lima Peru, this is about 50-100 soles, and I am planning to spend 20, so I guess I am carrying about 30-70 extra.
If you robbed me today, you would get less than 15 U.S. Dollars.
Generally when I read travel advice on money, passports, plane tickets and other important papers, I disagree with the mainstream advice. I use the money belts or neck pouches only when I move from city to another and I have all my belongings with me.
When a person tells me a story about being robbed, generally the there is a story because they was carrying something worth robbing.
Is there a difference between money and my camera, I always have my 500-dollar camera with me?
