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.
Godzilla (and offspring) featured in Toho's ShÅwa, Heisei and Millennium films. The initial series of movies is named for the ShÅwa period in Japan (as all of these films were produced before Emperor Hirohito 's death in 1989). This ShÅwa timeline spanned from 1954, with Godzilla, to 1975, with Terror of Mechagodzilla.
