Gordon comments about retirement:

from a #24-Jeff Gordon Q&A by Ryan McGee on ESPN.com:
McGee:‚ ‘This was your best finish in seven years. Under the old Chase system, you’d have finally won a fifth title. But we writers still come at you with retirement questions. So ‘¦ retirement?’
Gordon:‚ ‘I don’t believe in retirement, No. 1, but I know that I won’t always be a full-time Cup driver. That time is coming. Remember in May, my back got so bad I couldn’t get out of bed, let alone into a race car? So will that play a role in retirement sooner rather than later? It’s very possible. It seems to be the one limiting factor that I have right now. But there’s no plan. There’s no countdown. I’m racing.’(see full Q&A at‚ ESPN.com)(12-15-2014)
