I'm a convert, so the thought of growing old and accepting that is how I was raised....but still, after a couple of decades of systematically repeating 'Armageddon' will come before the generation of 1914 dies away, being systematically fed illustrations of youth and paradise - it is difficult for our minds to 'swap' the hope that paradise will get here before long and we won't have to deal with age and death.
Thats how we talked - we laughed and joked about our joy of knowing we'd never get old in this system - and now we have to live with something that is grittier and challenges us to grow in a real way.
I still believe in God and that Christ's coming into our dimension was 'light'.
To me, the Watchtower created a kind of 'spiritual materialism' ( I heard that expression elsewhere and it applies!)
We were always chatting amongst ourselves about 'the new system' - where we would live, how we would look and the improvements we'd like on our physical selves....
And now, the youth of JWs are having babies and families without a blink - whilst many of 'my generation' deliberately chose not to, as we showed our faith putting off the distraction of raising families.
Now, at 60 years old - I have no children with my husband .....I especially feel for him, as his siblings (non JWs) have big extended families of children, grandchildren family friends acquired through a life of 'doing life together' and old age is almost a rich pleasure to his siblings.
This 'spiritual materialism' which the WT created is not, I believe, the spirituality that strengthens in a true sense.....
You are young and you have the opportunity to make a difference to others, every day !!! focus on that, and the wrinkles will become your friend...
Well, that's how I see it - it's working for me :-)
