From psychology classes I've taken I believed the same thing - right up until having children of my own. I have two boys, one at 3 years and one 3 mos. The 3-yr-old has a female cousin that is only a few weeks younger. We've watched the two of them grow up side-by-side and seen how they appear to gravitate to male and female gender roles, respectively, with little prodding. ESB was on tv one day last summer and the boy sat up on the couch, watched the whole thing w/o leaving his seat. He noticed some of my old action figures in the basement one day and the rest is history (yeah, I know some of the material may be inappropriate for a 3-yr-old). When his cousin came to visit he wanted her to watch ESB with him, she got all excited, and was then disappointed and playing with her "girl" toys a few minutes in. Some of it just seems innate...

If you did RTFA, you missed the point. The idea is to use this on people for whom death is imminent. For example, a man suffering a heart attack. As the person "dies" you try to put him into suspended animation so the tissue never goes through "death". Once the patient is in suspended animation you have time to perform whatever surgical procedure necessary and then attempt revival. Other cases mentioned in which this will be used is severe bleeding - DARPA hopes it can be used to save soldiers who would otherwise have bled out and died.
