Your rejoinder
It might just be one never gets old prompted me to link it to Browning's quote because you had made it in reply to the quote. If yours was a stand alone statement and not a reply, I would have left it er...standing alone.
( Pst! There is a flaw in the reasoning. I'll be happy if someone points it out.)
Ah, the confusions of bull board posting in linear format.
My remark was more in general response to the Title assertion of the thread and in reaction to the general eagerness in all preceding posts to accept the premise unquestioningly. But flaw or not in reasoning, I don't see the virtue of branding ourselves as old because of shortcomings we can identify within our selves or our bodies, instead of considering how young we are when considering the brighter aspects of our lives. I am a long-time optimist, and negative thinking just drives me up the wall.
If one wonders where the logic is in that, I can only say that my entire life changed for the better when I shifted from worrying/pessimism to a positive, forward-looking approach to life. (And, free plug: credit Dale Carnegie for that.)
So, Gita, no personal argument with anyone especially. Just a statement of my own outlook.
And have a happy, positive day
