One major issue keeping people from traveling is safety. But, fear not. Generally speaking, traveling around the world is statistically no more dangerous than traveling across your hometown. Political violence and terrorism should be the least of your worries. But, there are dangerous countries. Just make sure to research the safety of the country you are traveling to.

Biggest Dangers: Crimes and Scams
Scams and crime are popular in tourist hot spots. When visiting a new area look up the local scams. Local scams can be found online, or in guidebooks. Word of mouth from other travelers should help you avoid scams, and other danger. There are a few other things you can do to avoid scams.
Don’t flaunt your wealth. Put your money in a safe place. Be aware of public distractions, and incredibly crowded areas. Pickpockets take advantage of these, and they can spot foreigners from a mile away.
Don’t get involved in get-rich-quick schemes. This includes gem export, exchange rate margins, and drugs. If it sounds too good to be true, then it probably is. And wandering around drunk at night could get you into some hairy situations.
You don’t need to get paranoid though. A little bit of smarts, and common sense will protect you from crime and scams. Just be aware of your surroundings.
