If you have a cut on the tip of your finger, don't despair when your bathroom first aid box only contains regular, straight plasters instead of those specialised fingertip bandages. You can make one with just two snips of your scissors.

I've been doing at least 10 burpees every morning since we started the burpee challenge. (One day of 10, actually, and the rest at least 30.) I've also spent a lot of time thinking, "Is this the right way to do a burpee?" and, "Is this the best way to do a burpee?"

Our skin can turn 7-dehydrocholesterol into vitamin D with just a little help from sunshine. With the winter pall setting in, you're probably not getting much sun, but no biggie - you can also get vitamin D from your food. You may be wondering though - how much sunshine is enough?

Five people have recently told me they were going to "try keto" — the most recent after gushing about a mutual friend who has been doing keto, aka the popular ketogenic diet, and getting awesome-looking results. You've probably heard rumblings about keto, but what the heck is it? And is it too good to be true?

Coin cell or "button" batteries are small, shiny, and feel tingly on the tongue. If you're a toddler, that puts them into the category of "belongs in my mouth". But a swallowed button battery can begin burning a hole through a kid's oesophagus in hours, causing pain, severe injury, and sometimes complications leading to death.

Hey friends, how's the burpee challenge going? Today I've got some modifications that will be perfect if the burpees haven't been agreeing with you, or if you're doing fine but you'd like to rope in a friend who has some doubts.

Is cage-free better than organic? Are omega-3 eggs worth the extra money? Let's break down the terms you'll see on egg cartons.

Every year on June 14, people around the world will donate blood in honour of World Blood Donor Day, a celebration to raise awareness of the need for blood and to thank all voluntary donors.

I don't believe in astrology, but I know my sign. (I'm a Sagittarius in the traditional system, Ophiuchus to stickler astronomers.) You could benefit from knowing yours, too! Just not in the way Dr Oz thinks.

Germs, like you and I, enjoy the warm and slightly moist embrace of a bath towel. (Hey, if it isn't moist when you first put it on, it gets moist.) But these germs are just here to cuddle; normal use of a bath towel is not likely to make you sick.

Core exercises will build up your abs, but they do nothing for the layer of fat on top of them. Likewise, no leg exercise can give you slimmer thighs. And yet headlines and tweets about shrinking specific body parts abound -- even when the articles themselves contradict the headline.

When I walk into my local cycling studio, the music is at a level that's easy to talk over. But once the instructor clips in, the volume goes way up. The sound fills your ears, so you can't hear the person next to you breathing heavy. You feel like you're inside the song, which helps you to really feel its energy. Perfect volume, right?

Taking time away from work when you have the flu or a sprained ankle is not only expected, but encouraged. But mental health issues sometimes require time off, too.

There's no magic force field that holds back germs while you shout "five-second rule!" and scoop up your dropped cured meat. Duh, right? Here's how you can prove it.

Non-dairy milks aren't perfect fill-ins for cow squeezings. They're made by watering down various plant products and their nutrition facts are nothing like dairy milks — or each other. A pair of scientists recently declared soy milk to be the most nutritious non-dairy milk. It doesn't really matter which one you put in your coffee, though.

We all need vitamins, but that doesn't mean you need to take a vitamin. This week, science gave us another brick for the giant "vitamin pills are useless for most of us" sign that's been under construction for a while. (It's a metaphor, but I imagine it as something like the Hollywood sign, except nobody looks at it because they're all busy shopping for vitamins in the valley below.)

We've all seen those transformation photos of people going from pufferfish-like bellies to enviously defined abs. You may have mused, "I wish I could get to that 'After' picture, too." Oh, but you can. Without actually being close to that great a shape, in fact. It's not honest, but marketers do it, and hot damn, you will look fabulous.

Last month, The BMJ published a case report about a 34-year-old man admitted to an emergency room in Cooperstown, NY with thunderclap headaches, a particularly painful kind that can be a sign of cerebral haemorrhaging. His symptoms included dry heaving and intense head and neck pain. The man traced his anguish to a chilli eating contest a few days prior where he consumed a single Carolina Reaper, the Guinness World Record holder for the world's hottest chilli.

A DNA-editing technique called CRISPR keeps popping up in the news, in one medical breakthrough after another. In theory, CRISPR can find any problem area in DNA, snip it out, and replace it with a fresh set of nucleotides. But in real life, that cut-and-paste job isn't always straightforward.
