This is a must read story about a 70 year old vet on a cruise stop in Costa Rica that takes out an assailant that tried, at gunpoint, to rob his fellow passengers. Here is some of the highlights:

SAN JOSE, Costa Rica - An American tourist who watched as a U.S. military veteran in his 70s used his bare hands to kill an armed assailant in Costa Rica said she thought the attempted robbery was a joke -- until the masked attacker held a gun to her head.

a U.S. military veteran trained in self defense, jumped out of the van and put the gunman in a headlock, according to Limon police chief Luis Hernandez.

Hernandez said the American, whom he refused to identify, struggled with the robber, breaking his collarbone and eventually killing him.

I think the story says it all.
