I was one of those spoiled nerdy kids who had about 10 shoe boxs full of legos, not counting the 15 or so "constructions" I had on my bookshelves and dresser. Honestly, I think legos had a real impact on my life. I was content playing by myself for hours with them. They made me a patient person, but they also made me a little introverted (at least by some standards).
However, I wouldnt trade my days (months, years?) of lego play time for anything.
BTW, I still have all mine (Ill be 20 soon). But my brother never got into them. He, at 11, a jock haha
