The Lego Architecture set with many interesting landmarks is very cool! You can build the Statue of Liberty!
They have small sets that let you do that and they have big sets too like the coloseaum or even the Taj Mahal
Lego recently released a new line of products just for adults. The Forma kits can help relieve stress.
I have built some of their art sets. they are very peaceful and fun. Plus you get a wall hanging at the end of it
You should build the koi fish! It comes with interchangeable skins!
I saw that. it's fun looking. they have a bonsai tree too that you can change the laves on. Even a set of a vase of flowers
Yes the different sets are fun and interesting and they may help with stress and anxiety.
I've even read about the business model and manufacturing. they are a very interesting company. I've played with their products basically my whole life
Legos were patented in 1958 and they have been fun for all ages and one of the most popular toys since then. 
In the late 90s early 2000s, they almost went bankrupt despite popularity
Yes but fortunately they made a comeback and made over 700 million dollars in 2011!
