The way to spend a healthy summer is to target those few key body parts that have been ignored during the winter months. Here's how:Body part No. 1: Cranking up the chromosThe chromoreceptor is universally found in humans and animals and is responsible for receiving tastes and scents. You can exercise your chromoreceptors most any time, but summertime fairs and festivals offer the most intense one-stop-shop excitement for this part of the body. A few thousand milligrams of kettle corn, hot dogs, funnel cakes and all other conceivable street-fair food (deep-fried candy bars included) and the chromos should be good to go. 1. Juneteenth Festival (June 18)-The oldest known celebration commemorating the ending of slavery in the United States, San Diego's Juneteenth festival includes live entertainment featuring local jazz, gospel, hip-hop and R&B artists, historical presentations and plenty of food and vendor booths. The event is held downtown at the corner of Third Avenue and B Street. 619-262-8384.2. San Diego County Fair 2005 (June 10-July 4)-Themed "Cinema Summer," this year's fair will highlight television shows and movies filmed in San Diego and Baja California. There'll be new special exhibits, but the traditional carnival rides and concerts-the real reasons to go-will be there, too. The fairground is located at 2260 Jimmy Durante Blvd. in Del Mar. 858-793-5555 or 858-755-11613. LGBT Pride Parade & Festival (July 30-31)-Possibly the most entertaining spectacle of the summer, this two-day party turns Hillcrest upside down, starting with the parade and continuing throughout the weekend on the west side of Balboa Park. (www.sdpride.org)4. San Diego Renaissance Faire (Aug. 6-7)-Spend the day with gallant knights and buxom wenches and experience the sights and sounds of the 16th century at Morley Field in Balboa Park. (www.sdrf.com)Body part No. 2: Giving the eyelids a restGiven the ridiculous amount of pure, unadulterated sunshine San Diegans get all year long, the height of summer is the appropriate time to give your eyes a rest. Here are some opportunities to stop squinting into the sun and go indoors for a different kind of visual stimulation. 5. Passion for the Possible: Serigraphs by Corita (June 5-27)-Known in the 1960s as the "revolutionary with a paintbrush," this former Los Angeles nun spread her messages of love, freedom and peace by using advertising slogans, Biblical Scripture, magazine photos and popular song lyrics.

Snapshot: From Box Brownies to Cell Camera (June 12-Sept. 18)-This exhibition displays family snapshots taken by amateur photographers during the past 100 years.

At the San Diego Museum of Art, 1450 El Prado, Balboa Park, 619-232-7931.Body part No. 3: Calming the nervesA perfect way to soothe your ragged nerves is through the outdoor-movie and concert-audiovisual experience. The sound of crickets and the smell of freshly cut grass, as well as the feeling of a warm summer evening breeze on your skin, are simple ways to pacify the nerves (you know, the ones that have been slowly constricting ever since the holidays).

It's important for children to get an adequate amount of exercise, and while parents are coaxing kids to do so, they should also do so themselves. The inner child should not be treated like a red-headed stepchild; rather, it should be nurtured like the pretty little honor student it is.13.

The perfect amount of sunshine is the sunshine you'll get in the time it takes you to walk from your car to a movie theater, where you will then sit for hours on end (out of the sun) enjoying one of San Diego's many famed film festivals.21. 2005 San Diego Film Festival (Sept. 21-25)-This year's fest not only promises to be entertaining; it also promises to be educational for those interested in the subject of screenwriting.
