I spent three months traveling through Central America. You really quickly get used to a constant sense of danger — the water and food can kill you, the bugs can kill you, the roads can kill you, the police and gangs could kill you — hell even taking a hot shower there is tempting fate since they have electric heaters in the shower heads and basically no electrical safety standards to speak of.
You either have to cower in your hotel in fear or live life. I went hitchhiking in Nicaragua, sledded down a volcano, went cliff diving, etc — stuff i’d never do at home.
There’s something to be said for facing down your fear of death and acting in the face of it.
