Read the following stanzas given below and answer the questions that follow each :
The sixth age shifts Into the lean and slipper’d pantaloon,
With spectacles on nose and pouch on side;
His youthful hose, well saved, a world too wide
For his shrunk shank and his big manly voice,
Turning again towards childish treble pipes
And whistles in his sound. Last scene of all,
That ends this strange eventful history,
Is second childishness and mere oblivion
Sans teeth, sans eyes; sans taste, sans everything.
(i) What happens with a man of age in the sixth stage?
(ii) How does a man look like in the sixth stage?
(iii) How does the voice of the old man change?
(iv) Why is the last stage called the second childhood?
