Yeah, I'd go with the first part of the answer as honesty, "I don't know and given the odds and experience of other top players in their 40's it seems unlikely".
The second part of the answer is a bit of bravado to both live up to the Tiger image of going for the heroic shot and the stupidity / tediousness of having to constantly address the question and having to deal with the media / fan fallout if he didn't sound less than 100% committed.
The guy was an excellent course tactician. Do people think he doesn't have a realistic sense of his odds?
The best deal I've heard of wasn't one that I personally got, but one that my friend got and then proceeded to brag about for a while. He found a Scotty Cameron at a garage sale, minor rust on the sole but no dings and otherwise in perfect condition, for $4. With a little gun oil and scotch brite he got it looking as though it were brand new off the rack, all for only the $4 at a garage sale.
