Absolutely. When I was doing a more full-time analyst thing, I didn't reuse content wholesale but there was often very little point in rewriting an explanation of some basic concept with different words. (And, yes, as to volume, it really adds up if you're doing 1,000 words or so most weekdays.)

If you listen to hours and hours of someone who does "speeches without notes" you start to realize how they do it - they have "building blocks" that they piece together in different orders.

When I was doing more presentations than I do today, I didn't reuse presentations (unless it was part of some sort company roadshow). But, yes, I'd reuse bits and pieces--often tweaked--rather than each presentation being created from scratch.
