Depending on the context, you might actually want to "stagger-breathe" to avoid breathing right on the phrase boundary. You generally don't want the breaths to be noticeable, especially if it's in the middle of a long sustained note. Instead, you'd take a breath on one measure mid-phrase, another player would take a breath in the next measure or so, etc. to keep the note going. When I marched in a drum and bugle corps, we'd actually all have individually preassigned breath marks.

Of course, this only works well if you have multiple players per part. This ain't really practical outside of marching or symphonic/orchestral contexts.
