Everyone's coming down with something at work and you can't afford to take a sick day. That, or you just don't want to catch it yourself. While there's not much you can do once you fall ill, there are steps you can take to minimise the risk and, hopefully, dodge the bug altogether.

A tap bought from Aldi by 12,000 Aussie households can contaminate water with up to fifteen times the safe limit for lead, according to reports. The ACCC has warned of the supermarket chain's "Spiral Spring Mixer Tap", urging customers to avoid avoid drinking or cooking with water from it.

The worst food poisoning I ever had was a few days after returning from a weekend getaway with friends. When I finally dragged myself out of the bathroom after 24 hours of hell, an email from one of my besties was waiting for me: "Is everybody else feeling OK? I know our dinner together was a few days ago so I'm sure it's not that, but I just wanted to check."

Luckily, Feevy is a new iPhone app that will help you track your child's temperature and progress, and report back to your doctor if things change.

Dear Lifehacker, After doing my research and crunching the numbers, I've purchased a brand new family car -- a Subaru Forester. One factor I didn't consider is the potential toxicity of the "new car smell". I can't find any recent research in this area, but I wanted to know: Are 2016 cars still susceptible to the same problem? Will the new car harm my infant baby?
