Julia Caples - a 45 year old mother of two from Pennsylvania (that’s Pennsylvania, not Transylvania) claims to drink almost two litres of blood every month.

Where’s she getting all this blood you ask? Apparently she hangs around the local occult and oddities shop scoping for human donors who will let her drink their blood (like the tattooed bloke in the picture).

In an interview with The Mirror she said: "When I feed off of a person and drink their blood I feel stronger and healthier. I know scientifically there's not a lot nutrition in blood, but maybe there's some value we haven't discovered yet."

Initially we thought, "oh god, here's some crazed Twilight fan taking things to the extreme" but apparently her blood sucking ways began over 30 years ago. She first got the 'urge' as a teenager during her first kiss:

"It was my natural instinct and I liked the taste, I just got an urge and can't really explain it. It's never gone away. Needless to say though, he never kissed me again.”

Sounds pretty bat-sh*t crazy.
