I’m Dr. Leeds from the university clinic. I have been asked to speak to you on jogging, that is running slowly.
    Now is running better than any other sport? Than manual labor? Exercise seems to be the key to health. And it should be constant and regulated.
    By constant I mean you shouldn’t study like crazy Monday through Friday and then run one hour Saturday and another Sunday. Do a little each day; a ten minutes walk is enough to start out with.
    When I said regulated I meant you should check with your doctor before you begin any hard exercise of any kind, especially if you’re over 30. If you run a mile a day and want to enter a six-mile race next spring, work up to it. Increase distance by an eighth of a mile, for instance, twice a week.
    Now a word about warm-ups. Don’t forget to do a few good stretching exercises before you start, five or ten minutes is enough.
    What about shoes? Good morning shoes are good to your feet. This can’t always be measured by a price tag. Look for a pair of comfortable shoes at a reasonable price.
    One more word: you have to figure out why you are jogging. If you are trying to make yourself healthier, you probably will. If you like to nm, if it makes you feel great, do it.
    I’ll be glad to answer any questions you might have over in the clinic. I’m in Room 530 and I’m available every day from 8:30 to 10:30 a.m. and from 4:00 to 5:00 p.m.
