Shocking study from cnn.com: Too much testosterone kills brain cells

I just couldn't help linking to this cnn.com article, "Too Much Testosterone Kills Brain Cells."

Excerpt:
"Too much testosterone can kill brain cells, researchers say, in a finding that may help explain why steroid abuse can cause behavior changes such as aggressiveness and suicidal tendencies.
Tests on brain cells in lab dishes showed that while a little of the male hormone is good, too much of it causes cells to self-destruct in a process similar to that seen in brain illnesses such as Alzheimer's.


[Barbara] Ehrlich's team [who led the Yale University study] tried the same thing with the "female" hormone estrogen, just to be fair.
"We were surprised, but it actually looks like estrogen is neuroprotective. If anything, there is less cell death in the presence of estrogen," she said.


"Next time a muscle-bound guy in a sports car cuts you off on the highway, don't get mad -- just take a deep breath and realize that it might not be his fault," Ehrlich said in a statement."
