I'm an AFOL (born in 1979) who has played with Legos since before I can remember. I was born during the heyday of classic lego space sets, which my older brother had collected, then I, too, once I was old enough to have the manual dexterity to build. Legos were the only toys I ever wanted, and I vividly remember wandering the Lego aisle at Toys-R-Us (RIP) and checking out all the classic castle sets and other themes that are so highly collectible nowadays. My dark ages started at age 15 when I sold my lego collection for 50 bucks.
My dark ages lasted from 1995-2015. I had bought a few sets here and there during that time, but I didn't really start building MOCs again until I was in my mid- to late-thirties. Now it's become an obsession, and my current collection far surpasses what I had as a kid. My awesome wife has been super cool letting me build my collection which has now taken over a room in our house. I plan on acquiring many more Legos in the future too.
I'm a geologist/paleontologist/textbook author who teaches at a large university in California. I'm also a Sylvan tutor, which gives me the opportunity to talk shop about legos with kids, who are typically surprised to meet an adult so who's so into Legos. I suffer from anxiety to the extent that it negatively affects my day-to-day life, and absorbing myself in sorting or building Legos helps me relax and center myself. I owe a lot to these little bricks.
