So it's the middle of the week, "Hump Day," and you're praying that the ass-end of the week won't be as stressful as the first half was. Instead of sitting in front of the TV with an aching back, trying to distract yourself with reality shows, why not head to the beautiful, spacious Desert Botanical Garden for &"Yoga Pura at the Garden: Chill Out" on Wednesday, August 17? Yoga instructors will show you how certain postures help to alleviate stress in the body, and how breathing techniques can help you relax and clear your mind. The class runs from 7 to 9 p.m., so you won't have to stress the sun; a walk through the Garden follows the session. All levels are welcome, and yoga mats will be provided. Required registration costs $12 for members, $15 for nonmembers. Call 480-941-1225 or visit www.dbg.org.
