Twins are a bit of a head fuck. Ever been mates with any? When you're drunk it's an absolute travesty. You could be at the urinals having a chin wag with one of them, then you leave and pass the other one as they're going in. "How'd you do that? You were just fucking in there!".
The problem is that you could be out of your face pissed, chewing their ear off about some bullshit like fancying some girl, but you're not entirely sure which one you're talking to. Because of that, and for drunkards that have no conception of identity, a lot of people will be in favour of this.
Last march NASA decided to send one identical twin brother into space for a year, leaving his bro down on Earth. The idea was to study them both to see if the vast nothingness of space altered Scott Kelly in anyway, differing him from his brother, Mark.

The pair share the same DNA so scientists wanted to look to see if Scott's genes changed while on board the International Space Station to get a better understanding of the effects space can have on the body.
Now back on Earth, Scott is reunited with Mark as the study continues to find results. The first batch of results have been released though, as biological samples from the two men, during, and after the mission are looked at, I Fucking Love Science reports.
The full results will never be released given the amount of sensitive information included, which you can kind of understand if it includes things like the shrinkage of man hood.
According to Nature, Scott's telomeres, the caps at the end of chromosomes, extended while in space, but then returned to their normal size when he touched down on God's green lands. This is contrary to what was believed to happen, according to Susan Bailey, a radiation biologist at Colorado State University in Fort Collins.

The twin's gut bacteria also differed. The 'bugs' that help in digestion developed over time, presumably due to the vast difference in diets as well as the environment.
Scott's methylation levels, a process by which methyl groups are added to the DNA molecule, effectively changing the activity of a DNA segment, were also found to be lower in Scott's white blood cells, whereas Mark's increased. " "These results could indicate genes that are more sensitive to a changing environment whether on Earth or in space," according to NASA.
Researchers found more than 200,000 RNA molecules that differed in Scott and Mark, meaning that scientists are "looking closer to see if a 'space gene' could have been activated while Scott was in space."

The biggest difference, however, is that Mark has a moustache.
Twins are usually inseparable, so it's odd that Scott and Mark spent 340 days apart.
A prime example of identical twins not willing to part is Lucy and Anna DeCinque, who married the same man.
From Perth, western Australia, they believe they are the 'world's most identical twins' and in the past they have undergone the same cosmetic procedures, including boob jobs, to ensure they look exactly the same. They met their boyfriend on Facebook and have been together for five years, so he's obviously doing something right.

The trio all share a bed and the women claim that they are never more than a few metres apart.
They've also said they would like to get pregnant together so their bodies will still be the same. So, looks like Ben is going to be busy.
'He's twinning and winning' the women modestly say in a video on their YouTube channel announcing their engagement.

Boyfriend Ben, who looks so fucking miserable in these photos but might just be exhausted, makes sure to treat both women equally at all times. "If he kisses Anna, he kisses me right after, and holds both of our hands when we're out," Lucy said.
In Australia, where the three live, it's illegal to be married to two people at once, even identical twins. However, the pair think that if they fly out to Tucson in Arizona they will be allowed to legally wed.
