Question 198461
Most of the time no hieght means no people hieght.  Use something else like dogs, horses, cats, dragons, of some other kind of animal.  Get a good excuse to get outside, see some animals and play a little.  Check your locale animal shelters, humane society, and pounds.  Tell the staff you have a project, but it isn't a test because most people don't like animal testing.  Have fun with this project.

PS. Maybe some unicorns too.
