This week’s links is a short one (two entire entries), as I’m being lazy. I believe in honesty, so there it is.

First up, a fantastic video on the evolutionary explanation of addiction (drugs, alcohol, nicotine, video games, sex, gambling, everything-you-enjoy-doing). It’s also an excellent intro to neurochemicals in the brain. ‘Mo’ synapses, mo’ problems, yo.’

The Scishow has lots and lots of other entertaining and informative videos.

And secondly, for the animal lovers, put together a Pet First Aid Kit in case of an emergency. Animals are people, too.
