Wow, this grew very quick
This all ranges from mid-life crisis to just seeing how valuable life can be. I don't know much in this area because I am not over 40 nor a female. I think that is very interesting fact that they had on this study.
Personally I am scared when I hit that age because I don't want my my just coiming out and saying "well after 25 years and a mid-life crisis, I just want to be single". This does make me double think marriage and life alltogether but I have to learn to except the heartbreaks of life.
