In 1940 Hilaire Belloc wrote to a friend:

“Old Age is, I do assure you, the most horrible lingering (and incurable) disease ever pupped or calved. It’s funny that the books lie so horribly about it! To read the books one would think that old age was a lovely interlude between the pleasures of this life and the blaze of Beatitude…But the reality is quite other. Old Age is a tangle of Disappointment, Despair, Doubt, Dereliction, Drooping, Debt, and Damnable Deficiency and everything else that begins with a D”.

[How about Delight?}

Hope this cheers you up!
