We've all been taught to wash our hands after using the restroom. But do we really need to? Let's take a look at the science.

This week we answer a burning question we have all asked ourselves at some point, 'how do I sort through pdfs?' The answer is simpler than you'd think, all thanks to something called "Optical Character Recognition".

Dear Lifehacker, My old boss was great. She and I got along, and she was a great manager. She got a new job and left the company, and they just hired someone to replace her. He's OK; he's just getting his bearings, so I'm withholding judgement. How can I set the stage early so he and I learn to get along well and work together?

Heavy alcohol consumption over ten years or more can cause significant brain function problems. But what about casual drinking?

Research reported last week found even moderate drinking could “damage the brain”. Considering 78% of Australians over 14 years old drink alcohol, this is understandably concerning information.

Dear Lifehacker, Lots of people are chronically late, and one big reason is the habit of always trying to do 'one more thing' before heading to an appointment. I suffer from this, and I've asked enough people to know that I'm not alone. Such people plan their day carefully, they know what time they have to leave, but they think 'I'll just do this one more thing before I go'. And that turns into another, then another, all small and probably non-urgent tasks that should only take up a few seconds but end up taking minutes, and then they end up late! Is there any way to deal with this? Thanks, One More Thing

On a scale of one to ten, how dangerous is TikTok for kids?

Although housing prices, according to some analysts, are cooling off, it's a fair bet that many of us are putting aside a significant portion of our salary on mortgage payments. We've crunched some numbers to determine where you should live if you want to have as much income left as possible once the bank takes their slice.

Did you forget to put the leftovers away? If it's only an hour or two, that's OK, but as the food temperature drops under 60 degrees, the risk of bacterial growth – and food poisoning – increase.

Newly-minted US Congresswoman Alexandria Ocasio-Cortez was a bartender when she pulled together a scrappy populist campaign and stunned the political world by unseating a powerful incumbent Democrat.

Her combination of charisma and radical politics has triggered the right wing and is striking fear into the Democratic Party establishment, with whom she's already pledged to do battle. This is her story.

Middle age is often seen as life’s pivot point. A hill has been climbed and the view over the other side is unsettling. As Victor Hugo said: “forty is the old age of youth” and “fifty the youth of old age”.

I took over the reigns of 'Ask Lifehacker' during my very first month at Lifehacker, and I’ve had a blast coming up with answers — occasional guesses, but mostly well-researched opinions — for your many tech questions.

So-called 'Greek yoghurt' has exploded in popularity in recent years, with Australia's major supermarkets all stocking multiple brands. It's now the number one choice for people who want a healthy alternative to normal yoghurt.

But hang on. Wasn't yoghurt always healthy? What's going on? It turns out there are certain health benefits — but also health drawbacks — to eating Greek yoghurt over the regular stuff. Let's take a look at the science.

Dear Lifehacker, I work for a company that will be shutting down between December 20 and January 12. We have been instructed to take annual leave - 13 days total - during this break. That's more than the half of my allotted leave. Is it legal for a company to dictate when you can take the majority of your holidays?

Dear Lifehacker, Are detox diets good for you, or just another pseudo-science? Does your body really build up toxins that affect you health and does a detox get rid of them?
