At age 45, Chris Downey had pretty much constructed the life he'd always wanted. An architect with a good job at a small housing firm outside San Francisco, he was happily married, with a 10-year-old son. He was an assistant little league coach and avid cyclist. And then - doctors discovered a tumor in his brain. He had surgery, and the tumor was safely gone, but Downey was left completely blind.
