We truly believe that building Lego's creates quality parent-child time, builds a child's spatial thinking and problem solving skills, and is where your child can find "flow" for the first time - that joyful space where your child loses track of time, only focusing on the challenge of building until complete!  My oldest is 32 and my youngest 18 - which means I've been stepping on Lego bricks for nearly 30 years!  My youngest is now a freshman in college, and has helped me sort, rebuild, and categorize all of our vast collection in order to sell them and earn tuition (out of state tuition is a beast!).  Purchasing from our store is a win/win - you finish your set and/or add to your own collection, and he becomes a biochemical engineer with less debt!  Enjoy the process :-)
