Tomorrow is an extension of today

What remains as I am getting older is the sheer reality of an ailing body, spirit, and soul. But it is also true that what I have done will outlive me. So, I exercise every day to keep healthy and try to produce something, amusing myself with new ideas, brushing up on new vocabulary, brainstorming about future research topics. At the root of my concerns lies the very fact that I will not be here forever. I will do what I can today. That is something I can achieve. Tomorrow is not mine, and if it comes, that is an extension of today.
