Shapely, lovely nails make hands look young and pretty, and a little colour or clear polish can really add a touch of class. But long, ragged and unkempt nails can add years to your hands. And your hands really are on show. Think shaking hands at a meeting, typing at work, putting your PIN code into the machine, taking cash out of the ATM - the sharp clack clack of untrimmed, uncared for nails is deeply unpleasant.
The same goes for your toenails. Think pretty pedicures and gently shaped nails, rather than long talons which rip holes in your tights and socks. The key to keeping your nails in check is to get yourself some good nail clippers which you can use to trim your nails down before filing them into your chosen shape.
In the same way that you look after your hair and skin, it is vital to look after your nails, too - good growth and healthy nails are a good sign of vitality. But you can also get dirt and other materials trapped under your nails and this can be unhygienic, another big reason to invest in a decent pair of clippers so you can keep your fingers and toes fresh and free from bacteria.
And if you're a biter, then stop right now! Nails that are bitten down to the quick look unpleasant and who knows what you are putting into your mouth when you bite your nails. It is more tempting to chew on long and unruly nails, so keeping them trim and short will help you avoid the need to keep having a nibble.
Giving your nails some attention every few weeks doesn't really take long, but the aesthetic and health benefits will start to show before you know it.
