In my research to make myself the premier personal productivity consultant in the northeast (hey - think wild success!) I've come across some very interesting ideas relating stress, aging, and unfinished tasks. What kicked this off was the article ABC News: '20/20' Busts 10 Body Myths, and this quote in particular:
"For one nagging unfinished task, it puts on about eight years on your life. So if you're 30, it makes you 38," said Roizen.
The connection to modern time management methodologies like GTD seemed clear: By getting control of those nagging tasks, we may actually be extending our life spans (in addition to the more commonly-discussed - and important - benefits of gaining relaxed control, maintaining focus, etc.)
