I've been building with LEGO bricks for so long that I'm not even sure when I first held a brick in my hand. It's likely that it was one of my older brother's bricks anyway! I'm an adult now, and I still have many of my more-than-30-something year old bricks even now.
Designing and building with LEGO bricks is what I now do with my son. He's able to build from instructions recommended for children older than he is, but, still, he'd just rather roleplay all day with whatever has already been built.
We have accumulated a sizeable empire of LEGO elements, and I have colleagues who believe I should get help for my addiction! I am grateful that MOCpages exists, because now I have a purpose for my brick problem; I can contribute to all of you who share my habit!
