Biological age test you can take?

Answer:
There is a free biological age test at www.growyouthful.com
It asks you about 140 questions, and then makes an estimate of your body's real age.
This test was the first available on the internet, and in my opinion is still the best available.
It also includes a shorter rate-of-aging test, to give you an idea of whether you are aging faster or slower than average
