Feel good all day!

Feeling fatigued after activities that used to be a breeze? Blame a decline in your body’s ability to produce the energizing brain chemical GABA, which typically declines after age 40. But spending just five minutes sitting comfortably and focusing on the present—like the sound of your breath and the sensation of your lungs filling with air—ramps up the production of this brain chemical by 27%, report researchers at Boston University School of Medicine, giving you a feeling of calm energy to power through the day.
