Unless you've been through it yourself, it's almost impossible to understand the feelings of people who've suffered loss of limbs or other parts of their anatomy, due to accidents or horrific diseases such as cancer.
In a bid to tackle this, one tattoo artist is offering out hyper-realistic tattoos for free - and the results look incredible.
Eric Catalano is an artist for Eternal Ink, a tattoo studio in Hecker, Illinois in the USA, where he provides the free service for victims and survivors of cancer and amputation, recreating nipples and even fingernails with ink.

Eric started his hyper-realistic tattoos back in 2010 as a way to raise awareness for breast cancer month - between 2010 and 2015 1,500 tattoos were done for free.
He explained that the tattoos grew more to be just ink and he started working a way to recreate the lost nipple.
He told LADbible: "The awareness raising 'trend' was just not enough. So, I got to work on parenting and inventing a micro dermal Implant that sits under the skin and has a silicone areola and nipple magnetised to the top as a way to give women a tangible nipple instead of just raising awareness."

From covering the blank skin left behind on people who've had a mastectomy with 3D realistic nipples, Eric went on to undertake new challenges, such as when he was approached by a man whose fingers had been partially amputated..
"This gentleman came to me last week asking for fingernails to be tattooed on his two nubs and I accepted," he explained - and now the man in question has two amazingly-real looking 'fingernails'.
Eric's reputation has now grown and he's since received thousands of requests for his hyper-real tattoos.
In order to be able to keep providing free tattoos for survivors and victims, Eric has set up a GoFundMe page, which in 12 hours raised more than $800 (£620).
He added: "I would love to continue helping survivors of trauma and cancer feel whole again by offering free services but now that this has taken off the amount of inquiries will be impossible to keep up with if I'm going to be doing my normal tattooing that provides my income.

"Three or four free tattoos a month to help people is no problem but this has the potential to be 30-60 per month or more if I reply to everyone and it continues. So, I'm faced with charging for my services which I don't want to do. So, I've sought ongoing crowd funding."
Eric's service is an incredibly noble one. Good luck, LAD.
