In their new book "Fiscal Fitness," fitness guru Jack LaLanne and investment adviser Matthew J. Rettick team up to offer "8 Steps to Wealth and Health" that they believe will help readers live well into their retirement while having enough money to enjoy it.

According to a statistic in their book, 57 percent of seniors have assets below $5,000, or less than the cost of one month of nursing home care. And only 19 percent of elderly people claim assets equal to three or more years of the average cost of nursing home care.

"The problems we have in America with obesity and the fact that we're just eating up Medicare and Medicaid with medical expenses because we're not in good shape amounts to a national catastrophe," says Rettick, CEO of Nashville, Tenn.-based Covenant Reliance Producers. "The No. 1 fear used to be dying shortly after retirement. But that's been replaced by the fear of outliving one's assets."

Your health and your finances are intertwined, the book insists, and lack of physical and fiscal fitness is all about risk. Follow these 8 steps, the authors say, and you'll be ready to leverage your longevity.

NEW YORK (AP) -- Oil prices soared more than $4 a barrel Wednesday as two big market drivers -- lower than expected fuel inventories and another slide in the dollar -- had traders buying in force for the first time in a week.

Prices rose across the energy spectrum, marking a reversal in sentiment from last week when falling demand for oil, gasoline and other fuels and a strengthening dollar pulled oil down nearly 10 percent from a record near $112.

The Energy Department's Energy Information Administration said Wednesday that gasoline and distillate supplies, which include heating oil and diesel fuel, dropped much more than forecast last week, while crude oil inventories were unchanged. Analysts surveyed by Dow Jones Newswires had expected crude supplies to rise by 1.7 million barrels.

Investors were already buying oil before the release of the report; the falling dollar, which was hurt Wednesday by disappointing economic data, again raised oil's appeal as a hedge against inflation.

Light, sweet crude for May delivery rose $4.68 to settle at $105.90 a barrel on the New York Mercantile Exchange.

"The bullish inventory report on top of the concerns about the dollar is just exacerbating the move that

For as long as I can remember, adding the phrase "like a girl" to the end of whatever you were saying was a put-down, an insult, something to come to fisticuffs over. Little boys the world over hated being told that they, for example, "threw like a girl." I'm not defending the statement, and as a member of the fairer sex, I certainly don't agree with its intent, but hey, that's been the case from the playground on up.

When it comes to investing, though, you could do a whole lot worse than learning to "invest like a girl." And that's why I'd bet Warren Buffett, chairman of Berkshire Hathaway (NYSE: BRK-A) (NYSE: BRK-B), wouldn't get offended if I told him to his face that he invests like a girl. In fact, he'd probably thank me (and perhaps slip me a box of See's Candies). Hang on to see why -- and stay tuned for our soon-to-be published book on this very topic.

What makes Buffett Buffett
What is it that makes Warren Buffett such a consistently phenomenal investor? Is it that he's zigging and zagging along with the market's every move? Is he trading all the time, buying this and selling that, racking up taxes and commissions all the while?

No, no -- what makes Warren Buffett the investor whom every investor wants to be like is that he approaches investing differently from the way most men do. He's patient and does thorough research. He waits for the right price to buy. He seeks to never sell the companies he invests in. He's the anti-trader, if
