The best investment tip of all is to invest in your health

Do you know what is the single most common cause of bankruptcy? Losing your job? Getting in over your head with debt? In fact, the biggest cause is getting sick. Almost half of all people who go bankrupt blame medical problems, and insurance often is no protection: Three out of four of them had health insurance when they got sick. Disease can ruin your finances by robbing you of income when you can't work, saddling you with bills that insurance won't pay, and even making it impossible to get new insurance after you recover because of your "pre-existing condition." Congress might act on these problems later this year. But even if it does, following a healthy lifestyle will still be important to protecting your family's finances—never mind the many more compelling reasons for doing so.
