Yes, we're all doomed.
The following is an actual conversation. I know because I was there.
New mother at her baby boy's first medical check up: "Hows my boy doc?"
Doctor: "I'm sorry to have to tell you this Mrs Jones but your son has a fatal, degenerative disease. With proper care and a bit of good luck, he might survive a 100 yrs or so, but sooner or later, he's dead meat"
Mom: "Oh doctor, is there nothing I can do?!"
Doc: "Not really, but make sure little Jimmy always suits up before he bones a tute."
