thank you foosnik for sharing this information. maybe this can explain why i have always been interested in the world "beyond", why i have a serious case of wanderlust, and why i am still single, and have no desire to procreate. whenever i see images of space and the stars beyond, i always have a sense of longing, and my chest just feels very tight. on the outside, i am fairly well adjusted, and people say i am pretty well grounded, with the exception of my need to travel so much. :d on the inside, i have come to accept that something got wired the wrong way in my head, and i am just an oddball. but maybe..just maybe...i am a wanderer, and am not crazy after all. lol
