I got 21... but I do agree like many others, that this test is limited mainly to Americans. Not only that but, we are not all equal. Some races do things better or worse depending on the environment in which they were raised. Also, size matters and appearance doesn't, in my opinion. If you have long legs and you are thin and have the proper muscles, such is the case in some cultures, then you may be better at running... as the example was given above; someone said they new of a country in Africa which has very fast people.
