The Mahabharata/Book 1: Adi Parva…
“ I shall with thy youth enjoy the pleasures of life for a thousand years.' To this Anu replied, 'Those that are decrepit always eat like children and are always impure. They cannot pour libations upon fire in proper times. Therefore, I do not like to take thy decrepitude.' Yayati said to him, 'Thou art sprung from my heart, thou givest not thy youth. Thou findest so many faults in decrepitude. Therefore, decrepitude shall overcome thee! And, O Anu, thy progeny also as soon as they attain to youth, shall die. ”
