Silly stuff...on a material functional level you're right of course. That's the effect of time on the body.....but in terms of being playful and open and spontaneous and adventurous I'm even younger now than I was at 40....and working my way up to 21 again! :-)Yes, we'll all get even older and even less functional...and there will be sickness and in suffering and death....and that's ok. It has to be ok as there is no other choice....but our inner attitude can be one of loving joyful acceptance which makes it more fun to live and more fun for others to be in our presence...and that's pretty cool! The tru measure of a life has much more to do with the quality of being than the quantity of functionality.Meanwhile, if you can read this and can still interact and communicate with others then you can make a difference for the future. You may never see the effects of your influence...in fact you probably won't, but that's not what's most important....what matters is that we all find ways to live a meaningful loving joyful life in spite of the misfortunes, infirmities and suffering that come with life.Maybe that's part of the value of becoming "old"? Eh? Robert F Kennedy, a man who died way too young.... said it well..."Each time a person stands up for an ideal, or acts to improve the lot of others, or strikes out against injustice, he sends forth a tiny ripple of hope, and crossing each other from a million different centers of energy and daring, these ripples build a current that can sweep down the mightiest walls of oppression and resistance."
