While I still think (hope?) the stock market has more good days than bad ahead, I'm starting to move into a little more defensive a position, shifting from 85/15 to 70/30.

Given that I don't expect to draw from my portfolio for at least 6 years, and that after that I can push withdrawals off another 2-3 years, at which point I'd still draw less than 3%/year, this seems to me to be sufficiently defensive.
