In case you haven’t yet realized that company-sponsored research tends to produce results that favor their products and marketing campaigns, have a gander at the amusingly transparent Pfizer Global Study on Sex and Aging. Specifically, check out the questions on the results page, and ask yourself “if I made Viagra [which Pfizer does] what answers would I want to see here?” Then click through and see their carefully researched answers to such questions as “do you agree with the statement ‘older people no longer want to have sex’?”
