Why the palms of our hands have lines on them
Regardless of whether you appraise yours critically, gape at it in admiration or avoid looking at it altogether, the human body is really quite amazing .
For example, not only do we have our own individual fingerprints, but also a unique tongue print too.
Our eyes can identity up to a million different colours and absorb more information than even the fanciest telecope.
And in one hour, our beating hearts will produce enough energy to lift a tonne of steel three feet off the ground.
But let's focus on our hands .
Specifically, the lines on our palms.
Palmistry would have us believe that these lines each correspond to our heart, head, lifeline and, sometimes our fate.

But the truth about these lines is (unsurprisingly) a little more rooted in science.
Business Insider has revealed the important function of these lines, which form in the womb around 12 weeks.
Rather than lines though, they are creases in our skin.
What this means is we're able to flex our hands easily, with the creases folding in, allowing us to be more dexterous and both hold and grab on to objects.
Most of us have three lines
Most people are born with three main creases on their palm, although the thickness, frequency and prominence depends on our genes.
There are rare cases when a person is born with just the one dominant crease running along the top of their palm, rather than three.
There's no science which supports these lines being linked to our fate
While, normally, it isn't symptomatic of any health conditions, it sometimes is indicative of Down's syndrome, fetal alcohol sydnrome, Turner syndrome, Aarskog syndrome and Rubella sydrome.
