I feel

Everything.

Life--the ups, downs, sideways, highways, byways, and other little nuances that make me know I'm alive.
Love--the sorrow, the joy, the euphoric splendors, the pain, the amelioration of hurts, many other things.
Knowledge--yes, one can feel knowledge. The weight, or lack thereof, the never-ending quest for more, the thirst and desire to learn things burning inside and outside.
Experience--the dry and dusty taste, like cold air, of learning from past mistakes. The sweet and fulfilling taste of learning from past victories. The dejection, the elation, the knowledge that things do go on and to learn from them...

I could go on forever, my friend, but I'll stop. Truth is, I feel and experience many things.
