Okay, guys, if for no other reason that this one ("Italians Come Out on Top in Penis Study"), please stay in shape and keep the WEIGHT down:
A group of scientists in Hong Kong spent five months from October last year measuring 148 ethnic Chinese volunteers aged between 23 and 93.
The average length of their flaccid penises was 8.46 cm (3.4 inches), which compared favourably with similar studies on other men overseas.
Germans have average lengths of about 8.6 cm, Israelis 8.3 cm, Turks 7.8 cm and Filippinos 7.35 cm. Italians were the longest at 9 cm and Americans averaged 8.8 cm.
The study did not measure the penises when they were erect.
Men, here's the part I want you to pay attention to:
It found that a man's height bore no relation to the length of his member, but those with higher body mass indexes, or fat content, appeared to have shorter penises.
"It seems that as someone gets older and fatter, his blood vessels change, so the penile size is not static. It may be a reflection of the condition of the person's blood vessels," Chan said, adding that this could spur yet another study.
Come on, men, let's all stay fit together...!
