I LOOK into my glass,
And view my wasting skin,
And say, "Would God it came to pass
My heart had shrunk as thin!"
For then, I, undistrest
By hearts grown cold to me,
Could lonely wait my endless rest
With equanimity.
But Time, to make me grieve,
Part steals, lets part abide;
And shakes this fragile frame at eve
Skilled in concise expression, Hardy states that younger people would have greater resilience to cope with the rejection of the women— ‘hearts grown cold to me’ — with whom he had relationships. Here ‘equanimity’ means patience and calm. 
 Most noticable about this stanza is the word order. The conjunction ‘For’ and the subordinate clause are placed at the beginning, and the verb ‘could … wait’ doesn’t appear until line three. This gives emphasis to the iniital description ‘undistrest/By hearts grown cold’, meaning untroubled or without pain caused by his failed relationships.  What the speaker wants most is freedom from the unhappiness that blights his life.
