Winter Hibernation!

A sort of weakness creeps my whole body; So tired and so low in spirit, my body aches! I feel I am sapped of all energy in such a way I feel like taking rest on the bed and nothing. What has happened to me at this stage of life? Is it due to old age that I feel so weak and dull Or the coming Winter effect makes me feel so? So haggard looking I have become exhausted! Nothing seems to bring me to my usual self; Without any briskness I simply coin words To make a poetry expressing my status well; But weakness within me makes me insipid...! Long night sleep also seems to be not enough; Perhaps this is stage for hibernation for Winter!
