Right click on download under a podcast listing, then click on save as to download a podcast. These are radio shows at 32 kbps mp3 without the commercials, so they don't take that long to download even if you are using a dialup connection. Since they are without the commercials and without news headlines, an hour show plays for around 36 minutes. There is some great information given in these radio shows. Dr. Hoffman is an MD who practices in NYC and uses nutritional supplements as his first treatment choice, but is not afraid to use prescription drugs when they are really needed.

Do you know of any other good health related podcasts on the net?
