RESPONSE: If the steroids make bigger beefier cattle over a shorter time
period, wouldn't they make bigger, beefier (as opposed to obese) humans?

The other point to consider is are these steroids heat stable ?
Most beef these days is cooked to at least 80 degrees celsius (I don't know
what this is in fahrenheit) at the core of the meat (and over 200 degrees
celsius on the outer surface).  Can these molecules retain their biological
activity after this treatment?  Does anyone know?

its an interesting correlation that you have mentioned Diane, its bound to
draw a lot of comment.  OTOH, there has been a lot more processed food
available in the last 30 years.  i look forward to the development of the
