    According to a study of 2,000 people by the British College of Podiatry, one-third of men and more than half of women wear shoes that don't fit properly.

    A study by the American Orthopaedic Foot and Ankle Society found that a whopping 88 per cent of women in the United States wear shoes that are too small — and 55 per cent have bunions, often due to those ill-fitting kicks.

    Pregnancy, injuries, weight changes and other factors can influence the shape and size of our feet, sometimes just by millimetres. We may not realize it, but these subtle changes can often amount to a new shoe size.

    "I must say I find it interesting because we do only measure our feet as a child and then don't once we are grown — and just assume we are always the same size," Natalia Barbieri, co-founder and designer of Bionda Castana tells British Vogue.

    Online shopping "receives a measure of the blame for shoppers buying the wrong size," Vogue reports, as buyers

  • If you find yourself reaching for a cold beer only to discover that the only cans remaining are — gasp! — lukewarm, life-hack expert DaveHax has you covered.

    That beverage can be ice cold in just two minutes, using only a bowl of water, some ice, cooking salt and the second law of thermodynamics.

    "Basically, adding salt causes the ice to melt faster. But to do this, it needs to draw heat energy from wherever possible, in this case, out of our can, causing the drink to rapidly cool down," DaveHax explains.

    He claims you can use this method on almost can canned or bottled beverage.

    DaveHax has a few other tricks to make our lives easier:

    Grant Thompson, "The King of Random," offers a more time-consuming cold-beverage trick: the instant soda slushie. (The "instant" part comes after your bottle hangs out in the freezer for over three hours. No immediate gratification here.)

  • Two Harvard students are about to revolutionize the way we make cake with their brilliant patent-pending invention: SprayCake.

    Gone are the days of craving a cupcake at midnight but being too lazy to whip one up from scratch.

    With SprayCake, you can simply spray one out of a can.

    Think whipped cream in a can — but with organic cake batter.

    TIME's Tessa Berenson explains how it works:

    "The accelerant in the can releases air bubbles inside the batter, eliminating the need for baking soda and baking powder so the confection is ready to eat almost instantly. It takes 30 seconds to bake a cupcake in the microwave, and only one minute to bake a full cake."

    John McCallum, a Harvard junior, came up with the idea for his final project in a Science and Cooking class.

    "We had a final required with the course," McCallum tells ABC News, "and we wanted an excuse to eat a lot of cake. Spray Cake is the excuse I came up with."
