I get what you're saying Joey, this pimi JW doesn't want to acknowledge he's been waiting for the paradise his whole life and now he's well into middle age. If he's says he doesn't feel old then Armageddon is not delayed, the GB aren't lying.
It's not surprising that he's talking about how he feels because the whole religion is about appealing to people's emotions but as you say ten years down the line if health problems kick in it might be a different story.
