Utah's chief executive officer needs more sleep; and like his fellow Utahns, Gov. Mike Leavitt needs more balance in his life.

But a comprehensive physical exam Wednesday - his first in several years - shows the state's top dog to be in good health."Generally speaking, they told me I'd live to be a hundred," Leavitt said after a two-hour workup at LDS Hospital's Fitness Institute. "Well, a little short of that, but they think I'm a pretty healthy fellow."

The governor does pretty well on the health front, and Dr. Richard Ingebretsen was complimentary about Leavitt's habits.

The governor's black Lincoln Towncar makes its way through the McDonald's drive-thru "more often than it ought to," by Leavitt's own admission, but he walks a few times a week and tries to watch what he eats.

To the public eye, he is trim and seemingly inexhaustible.

Sleep. That's the problem.

He won't admit how little shuteye he gets each night. "It's embarrassing," he said. "It's something I've got to work on. I know I feel better when I'm more disciplined about it."

The governor's schedule of daily activities shows him up early doing the state's business and often working late into the night at functions, meetings and events. He also travels a lot.

"I have a job that has lots of demands, and it's difficult to maintain balance sometimes."

After Wednesday's exams, Leav-itt vows to try harder.

Family, friends and colleagues had been twisting Leavitt's arm, urging him to get checked out. Nothing was wrong, he said, but it had been several years since his last checkup.

Doctors and staff ran a battery of tests that included a blood panel, urinalysis and an evaluation of cholesterol, triglicerides and lipoprotein levels.

"They did all the normal poking and prodding they do for a person my age."
