Here's a remarkable figure: $3,580. It's striking because it's apparently the donation amount it takes to save a life overseas.
Most of us probably don't have that amount lying around the house, but it certainly wouldn't take many of us to scrounge up the cash to make a life-altering difference for someone.
It's a challenge to be an expert in empathy these days; to step in others' shoes and feel what they are going through. (Just ask my wife – she'll confirm I'm often clueless.) We're easily bubble-wrapped in our isolated worlds.
Luckily there's a long-time tradition at the end of the year of donating to those in need. This helps us get our heads in the right space to go charity shopping.
Nowadays there's a movement towards "effective altruism" – funnelling dollars towards where they will make the most difference. Where do we get the best results for our money?
