A coworker from when I was at EDS, who was about five years younger than me, was diagnosed with a brain tumor in January, and died this week.
My sister in law, who does all the right things, found herself abruptly weak and feverish, and with periods of either double vision or vision in just one eye, before they found a lesion on her spinal cord that could be part of the problem. She's four years younger than me.
Live now. Exult now. Tomorrow, you may be too weak, or too dead.
