coming to the point ! or rather '7' was wondering about horcrux's for those of you are not a HP fan ;( here is the wiki definition of the horcrux
A Horcrux is a fictional magical object in the Harry Potter series by J. K. Rowling. It is a Dark Magic device created to attain immortality. The concept is first introduced in the sixth novel, Harry Potter and the Half-Blood Prince, though Horcruxes are present in earlier novels without being identified as such. Rowling uses the character Horace Slughorn to introduce their properties. The retrieval and destruction of Lord Voldemort's Horcruxes forms the main focus of the final two books in the series, Harry Potter and the Half-Blood Prince and Harry Potter and the Deathly Hallows.
come to think of it we all have horcruxes dont we... and in real life we have more than 7. we / others leave footprints (memories well more bad than good) on each other thereby making ourselves immortal (so to speak).
what happens when someone tries to rubbish your memory with others once you've left do you actually go back in time and correct every perception or just say f**k it (keeping it clean hehehe)...
then there are those times when you actually feel you had'nt met / known a few people EVER.. or they would not be carrying your horcrux for you. i hope sometime in the future there is a brain explorer wherein one could simply delete the parts (files / folders) well not delete PURGE the parts which are now full of virus'
anyway enough bout horcruxes.. :)
