High density lipoproteins, or HDL's, are good for you. They are produced by the liver to carry cholesterol and other lipids (fats) from tissues and organs back to the liver for recycling or degradation. Having high levels of HDL lowers the incidence of atherosclerosis (clooged arteries) and heart disease.

The ways in which you can increase the HDL levels are:

1. Moderate exercise (about 30 minutes five times a week) not only reduces LDL cholesterol, it also can raise HDL cholesterol, too.
2. Smoking can lower HDL levels, in addition to disturbing other aspects of your lipid profile. This appears to affect women more than it does men.
3. Eat healthy by including lots of fruits, vegetables, whole grains and lean sources of protein in your diet. Also be sure to include monounsaturated fats in your diet.
4. Moderate consumption of alcohol may also positively impact HDL levels.

You could state a  restaurant boring if

if you haven't made changes in your menu in the last two years. (Price increases don't count)
if you haven't updated your decor in the last five years
if you do not provide continual education for your more experienced workers
if you are only as good as you need to be to stay competitive
if you wait until someone else has proved an idea will work before trying it
if you have not had some spectacular failures in the last three months
if you are the only one in the operation authorized to make a major decision
if you regularly lose talented staff
if you do not visit restaurants outside your market area and find new ideas to adapt
if you never run special promotions or food festivals to break up the routine
if you (and your staff) do not know the names of your regular guests
if you do not receive requests from guests to have specific staff members serve them
if you are regularly working more than 60 hours a week
if you -- and your staff -- are not having any fun
