Just watched a cool Ted talks video about rats!
These rats are "hero rats." Some are trained to sniff out land mines, others to sniff out tuberculosis.
The director of the program is a guy who quit his job as an engineer to solve some of the developing world's most pressing problems. I admire him.
I'd like to donate to the cause. Have to figure out my reluctant PayPal account first.
Those rats are both clever and cute!
