A great way for me to get quick overview of the world new and make Iran still exist... I picked up on this story about a man who swam the Amazon River from beginning to end.
My first thought was, hmm, wonder where he chose or how he chose the location of the beginning of the Amazon. I mused on this point too much and have spent time looking at maps, while in Bolivia and think the very start is around Santa Cruz, Bolivia.
I got immediate fear thinking about swimming down the Amazon. I cringed and imagined a Piranha going for my privates. I have swam in the Amazon but while with great self-talk saying continually to myself, - They will not bite me, this is just a story, and happens only in movies.-
