Climate change used to seem like something that would confront our grandchildren — a distant concern. Now, though, it’s staring us right in the face when we get up in the morning.

Often, there’s a moment early in a medical emergency when you know something is wrong, but aren’t sure you want to call 000. When I reacted to some antibiotics by breaking out in hives earlier this year, I stared at my phone for about 15 minutes before calling 000 — I knew something was wrong, but I didn’t know what to do and I wasn’t sure that the problem was so urgent that I needed ambulance, which is a real expense even if you have insurance.

Remember when you bought a new can opener because you thought you lost your old one? What do you plan on doing with that half-used roll of duct tape that's collecting dust in your garage?

Hey there preppers! Remember when we talked about Doomsday Prepping for Non-Paranoid People? About how, in these uncertain times, we should all have a well-stocked emergency kit, or in my case, an emergency cabinet? If you acquired the basics of water, food and gear six months ago, now is the the time to open your kit and check that your supplies are still functional, edible and potable. You don't want to want to be mid-disaster and realise your batteries leaked corroded crusty goo all over the Kind bars.
