I have a friend who is one day older than me. I would certainly say that we have different aspects of our personalities, but I am sometimes amazed at the similarities in our life-paths. When I met him, I knew before knowing that he was my soul brother (which, by the way, is said somewhat tongue-in-cheek), and was not surprised to learn how close in age we were.

Not just an interesting question - a fascinating one.

I once came across a whole set of stories about all the mind-boggling coincidences that ssem to beset the lives of adopted twins who are only reunited later in life: things like each marying and divorcing spouses with the same names in the same year (in each case), having children as well as pets with the same name, liking the same brands of beer, food or cigarettes, and finally getting heart attacks or dying withing minutes of each other.

Apparently, Tiberius's astrologer Thrasyllus saved his own skin when his employer threatened to behead him for giving him ambiguous readings, by telling him that as his time twins, if he were to die, then Tiberius'own demise would be sure soon to follow.

Poe later on was also to write that you did not need to be a biological twin to follow in this tendency - you only needed to have a time twin - your Doppelganger. 'William Wilson' is a tale where the time twin's life also dovetails with the other in thoroughly spooky fashion.

And apparently, these spooky coincidences between time twins do happen in real life too - well, John West made a point of ctaloguing these things in his book, The Case for Astrology. Especially, the bit about time twins dying at the same time, as well as getting married, or starting businesses at the same time. There is also a photo showing what appears to be too identical twins - well, the two young grils are twins. But not biological twins - time twins.
