DEAR HARRIETTE: My oldest daughter is preparing to head to college in the fall. She has worked so hard over the years – as a student and as a sister. Her father and I spent a lot of our time working, and she picked up the slack with her two younger siblings.

Dear Doctors: I am 72 years old and in good health. Last fall, I got weak and shaky while working in my yard. It was a hot day, so my son insisted on calling 911. They said it was heat exhaustion, and I got treated on the spot. How is heat exhaustion different from heat stroke?

• Have you ever thought about how unclean the inside of your car really is? Many of us rarely clean the interior thoroughly, even though our car is a second home. Some independent studies have shown that cars can harbor mold, mildew, bacteria and high levels of unhealthy volatile organic compounds (mostly due to those artificial car fresheners dangling from the rearview mirror). To detox your car, mix a 50/50 solution of rubbing alcohol and water and wipe all of the surfaces down with a microfiber towel. Then ditch the air fresheners altogether!

• When storing leftovers in the refrigerator, it’s imperative to cover the food to keep it fresh. But did you know covering your food also helps save energy? The compressor inside your refrigerator is what keeps the air inside cool. Moist air is harder to keep cool, so uncovered food, which emits moisture, causes the compressor to work harder, using more energy. Investing in reusable silicone covers or foil to cover food is a simple and easy way to keep moisture out of the air and help save energy and money.
