In the United States, I would say 6' is the magic number (because of being an exact number of feet). That would be 182.9 cm. I'm sensitive on this point because I used to be 5' 11-3/4" (five feet, eleven and three-quarters inches = 71.75 inches = 182.2 cm. Nowadays I only measure 5' 11" and any day now I will probably fall below, which will be tough after so many years of being able to say, honestly, "five foot eleven."
Wikipedia says the average height in the U.S., all men of all ages, is 175.7 cm (5 ft 9 in).
Once I hear a doctor on TV talking about the ideal height for men, it was between 1,73 cm until 1,77cm. He was talking about impotency and also about the lack of inadequate blood pressure. Between that height mentioned before there is most chance to be the golden number (beauty's number).
I do not want to scare you, but you better take precautions.
