Around the world trip; sounds good!!
Uhmmm, you say ‘if something happens’, well let’s see:
Learn some basic martial arts, and kick butt, if necessary;)
Don’t put everything in 1 wallet, but keep always a emergency wallet somewhere else
Put the most important telephonenumbers on speeddail; you can block credit cards / contact your embassy faster
And you’ll definitely meet people to travel along with, during your rtw trip
Do you have already in mind where to go to??
Bye; Andreas
