Me, I've never entertained the teeniest speck of desire to actually go there, but I have read a lot of books about it and seen a lot of documentaries, and indeed, it is fascinating.
One grandson-in-law, working on his post doctorate in Biology, went for 6 weeks in January/February a few years back with a shipload of other scientists. He emailed back and forth with my daughter Becky's First Graders in Kansas City, Missouri and both sides, Aaron and the kids, had a ball. The ship's times for emailing were confined to a certain portion of the day, something to do with where they were, I don't remember the details of that, but Aaron would receive an email with 3 questions the kids had and then the NEXT day he would send them his answers, with photographs of himself and the ship and all. It was a great learning experience for the kids, Becky, me, and Aaron swears himself!
I do not like to punish my body, and my body likes not COLD temps!
