I do look at our pensions as the bond portion of our investments (so our investments are 100% equities), but I'm not planning on a higher withdrawal rate, largely because we are close to the age when we can collect already. Ours are very stable government pensions, and we each have one. They don't adjust for inflation until we start collecting, but after that they do.
His doesn't include health insurance, but mine will cover both of us if I work until the age I can collect, so I likely will. Odds are I'll need to, anyway, plus I like my job and have a great deal of schedule flexibility (college professor).
