Testosterone levels peak during adolescence and early adulthood, and begin to decline after the age of 30 at the rate of about 1 percent each year, but low levels can be caused by stress, a bad diet, obesity, and other factors.
The first film, Godzilla, directed by IshirÅ Honda, is an early and influential classic in the monster film genre and was initially released by Toho in 1954. Utilizing an hydrogen bomb incident to unleash the monster, the film tapped into political undertones and feelings common to Japan at the time.
Japan continued with a giant moth in Mothra, a turtle in Gamera, and many more that followed. Other countries have their own giant monster movies such as the United Kingdom with Gorgo in 1961. Films featuring Godzilla and Gamera were made into the 1970s, and a King Kong remake was released in 1976. Awareness of toxic waste in the 1970s inspired the release of various horror films, and the giant monster subgenre saw the release of 1971's Godzilla vs. Hedorah.
