and having plenty of energy to do yard work in 100 degree humid air
Jezebelle and I have an unbroken streak of having a watermelon everyday since April. It cools you down instantly and acts fast for energy while being low calorie. It is key. Always go for the yellowest ones with the largest flat spot you can find. The yellower the spot, the better. Sat longer on the ground, developing sugars and flavor.
Actually, eating cucumbers would be key. Cucumbers cool down your body.
