Using Arel to compare attributes of a record

I was just trying to find a way to run a query and compare the updated_at and created_at attributes of a record and came across this technique:

users = User.arel_table

It seems like .gt and .lt also work. While User.where("created_at = updated_at") would also work in SQL, we can use Arel to be database agnostic.
