Aging and experiences of reaching midlife and why it is the era of loss. For some it means not being able to eat like the teenager they once were. Eating what we like means seeing the scale increase a little more everyday, or spending a sleepless night with heartburn or in the bathroom. For others it means the injuries they sustained in their youth now begin to hurt and slow them down, getting in the car just to drive across the street. And for others still it means the living to work as they enter the most productive years of their lives.
