A study was printed in Psychology Today (maybe six years ago), that followed identical twins separated at birth. It turns out that their "chosen" professions, their wives and husbands, their pets, the timing of significant events, etc. all matched up like a pre-programmed sequence. So, for example, with one set of twins, they both became fire fighters, dressed alike, had the same kind of glasses, same kind of home life, etc. I think the article was titled Nature vs. Nurture. The conclusion was that we are not as free as we like to think. Who knows of some follow-up articles or resources along those lines? And does anyone know the original publication data of the article from PT?
