“How ya' doing?” tumbles out of my in-box a dozen times a day. Surprisingly, most of the queries are from people I've never met. When they provide a valid e-mail address I tell them I'm doing fine and thank them for asking but most aren't meant to be a medical report; most are a simple show of solidarity from one airman to another. And as I've said to them, it is warmly appreciated.
As for the purely medical aspects of 'How ya' doing?' I've completed the radiation therapy phase and have started on chemotherapy. The pain is pretty much under control, my weight-loss appears to be flattening out and I'm getting more sleep. Overall, I think you can say I'm one lucky fellow.
Some say we make our own luck. I've got good evidence that much of it is a shared commodity, transferred from one individual to another by something as simple as asking: 'How ya' doing?'
Just fine, thanks. But a lot of that is because of you.
