When looking in your fridge, do you ever wonder if certain items are still good?

I love summer salads, but I don't eat as many of them as I'd like to because it's so hard for me to keep lettuce and salad greens fresh in the refrigerator for more than 1 day at a time. But it seems FitSugar has the answer, and who knew it would be so easy? Just put your greens in a plastic bag, breathe a puff of air into it (for the carbon dioxide) and tie it at the top. Of course it will take up more space in your fridge this way and I'd make sure your family isn't sensitive about people breathing on each other's food, but if this works (I'm totally trying it) what an awesome trick!

A common challenge of exercise is figuring out how hard you should work. There are a few options to calibrate the ideal effort you should be putting forth, but most require too much math to make them great mid-workout options. I like the Keep It Simple Stupid version called the Talk Test.

For the average healthy individual who is trying to improve overall fitness, including cardiovascular and lung capacity, these are the rules.

• If you can have a full blown conversation during an aerobic workout you should be working harder.
• If you can't talk at all, even to scream "help!", you are working too hard.
• If you are huffing and puffing, but still have enough wind to tell your partner or trainer, "I can't wait to get this over with"...your pace is juuuuuust right.
