Forty is old but midlife is young old age

What they don't tell you about growing older is that 40 sounds old but mid-50s is young again. In your 40s you're always comparing yourself to your past self—abilities, appearance, energy, ambition. Once you cross into your 50s you start looking around, and really seeing, the folks in their 70s, 80s, 90s...and boy are you glad you are still young. A young senior is younger in attitude and gratitude than an aging middle-ager who is too preoccupied with resisting to practice accepting the inevitable.
