“Now, if groups are going to a bar, then one should be a designated ‘safe rider,'” warned health professor Robyn Gershon, the study’s author.

Between 1990 and 2003, 145 of 315 unintentional deaths came when boozy riders stumbled off the platform, fell suddenly ill or, in acts of liquid courage, jumped onto the tracks to retrieve a personal item.

Drunken riders died at higher rates than those who were killed or committed suicide. And today’s economy might not help the equation.

“With the changes to the financial picture in New York, there’s talk of an increase in alcohol intake,” Gershon said.

That’s enough for every man, woman and child in the city six times over.

It was more than double the previous year’s 17,770,000.

The price tag of the rubbers was put at $1,054,228, which doesn’t include the bill for some 2 million female condoms.

New Yorkers collectively outsweat Los Angeles, Chicago and even Houston.

For the fifth year in a row, Phoenix, Ariz., was named the sweatiest U.S. city with an average summer temperature of 95.1 degrees, according to sweat expert Dr. Jay Gooch.

The city came in 49th place in the survey conducted by a global consulting and investment firm, Mercer, dropping from 48th in 2007 and 46th in 2006.

Zurich was listed as the international city with the highest quality of living, followed by Vienna, Geneva, and Vancouver. The top-ranking American city is Honolulu, which came in at 28th place, followed by San Francisco, in 29th place. Boston is ranked 37th, and Chicago and Washington, D.C., tied for 44th place.
