Inspired by Vamos' thread about keeping up with technology.
Here's some things that genuinely cause me small amounts of stress
1) Guilt at eating food that isn't healthy
2) The depleting tuna problem
3) The bit of petrol that is wasted at the end when you fill up your car
4) Endangered animals, including the pygmy sloth :'(
5) The pollution levels in London and how much shit I must be breathing in (including black snot from tube)
MOAR? Unless I'm the only mental one.
