Compare the 1st and the last stage ?

JUST AS A MAN IN HIS INFANCY IS ABSOUTELY HELPLESS AND TOTALLY DEPENDENT, MAN IN THE LEST STAGE OF SANLITY TOO BECOMES TOTALLY DEPENDENT ON OTHER. WEAK AND FEEBLE, WITH ALL HIS SENSES FAILING, HE IS NOT ABLE TO DO ANYTHING HIMSELF. TOOTHLESSLIKE AN INFANT HIS VOICE TOO BECOMES LIKE CHILD. IT IS AT THIS STAGE OF LIFE THAT HE STANDS AT THE THESHOLD OF DEATH.
