More on the story of the 90 year old whose track record was stripped.

I believe the guy.

I recently read something about the use of hormones in beef raising
and while the article didn't say so it appeared that most commercially
raised beer is treated with growth hormones. The article states that
"500 grams (~ 1 lb) of beef from an implanted steer contains
approximately 7 nanograms of estrogen compared to 5 nanograms of
estrogen from non-implanted beef.
Furthermore, there are many common foods that are naturally much
higher in estrogen than implanted beef. For example, 500 grams of tofu
contains 16,214,285 times the amount of estrogen compared to the same
amount of implanted beef".

On the other hand the liver does act on hormones:
"The normal liver function depends upon the amount of hormones in the
blood which is regulated not only by the endocrine glands (EG) but by
the liver itself to a large degree. The hormone content in the blood
may be normal, when the EG function is increased, if the liver removes
them intensively, inactivates them and excretes in the bile. If the
hormone excess exceeds the regulatory capacities of the liver, their
level in the blood increases."

But a 90 year old athlete isn't that rare :-) Fauja Singh, born 1
April 1911, is a British Sikh centenarian marathon runner who among
other endeavors, participated in the Hong Kong marathon in 2013, five
weeks shy of his 102nd birthday, completing a 10 kilometer run in 1
hour 32 minutes and 28 seconds.

for more old geezers that run fast :-) The same site also lists a
bunch of old ladies that run fast :-)
