I am online at SL now since the beginning of March 2009 and it's funny to see how by even entering this virtual world the power of blood can't be resisted. Yes I write in rl too but with one difference. In rl I make money with it :p And no, English isn't my native language but being in SL is a great way to improve that.
I come and go in SL and will write here only about my experiences in SL.
This picture shows u an example of MHS. It's actually funny that it appears mostly at the end of summer. SL scientists believe there is a connection with Halloween. The name "Halloween" is derived from Old Irish and means roughly "summer's end". So what has the MHS in common with Halloween you might think. When summer ends a lot of people, especially women, start to feel more depressed because they tend to think too much about the upcoming cold period of the year: changing their wardrobe, paying the heating bill, worrying about their hair getting wet in the rain etc. The appearing of the melon shape on their heads in sl shows you the level they worry. The larger the shape the more they worry. As long it stays white or yellow there's no cure. Only thing that can be done is to take antidepressants. But when it turns orange before the 31st of October best is to carve it like a jack-o'-lantern. Your mood will improve immediately.
Sorry ladies... I should have written this one before Halloween 2010 but unfortunately I had no time to do so.
