That is, as close as I can calculate, the sum total of time Wendy was in my life: from the moment I met her until the time of her death. That duration represented 23.9% of my lifespan, a percentage that will only decrease as I continue to live. For example, if I managed to live to exactly 100, the Wendy years would constitute 8.6% of my lifespan.
