One of my psych students asked me a couple a question regarding sexual
orientation: Is there a gender difference in age of awareness of orientation
(i.e., are males who are homosexual aware at an earlier age of their
orientation than lesbians), and if so, why? I've never seen this addressed
in the literature and was wondering if any of you had.
Also, I received an examination copy of Psychology and Life - 15th edition
(Zimbardo & Gerrig) and was surprised to read the following on page 91:
".... Students have often asked us, for example, whether it's true that
brain cells die if students have too much alcohol or too little sleep. The
short answer is "yes," but the long answer is more reassuring: As we
mentioned earlier , your brain starts out with between 100 billion and 1
trillion neurons. Those neurons die out in astonishing numbers -- somewhere
in the neighborhood of 200,000 each and ever day of your life (Dowling,
1992). Fortunately because you start out with so many neurons and because
some types of neurons are replenished, you would lose only about 7 percent
of your original supply in 100 years.
Dowling, J.E. (1992). Neurons and networks: An introduction to neuroscience.

Is anyone out there familiar with the work cited? Are there other studies
supporting the neuronal loss figure? How much alcohol are we talking about
and over what time period? How much lack of sleep?
Thanks in advance for replies
