OK. _________________(To conclude; To sum up), there's still a lot to learn. We're _________________ (just beginning; only starting) to find out how pain control and mental health are different in men and women._________________ (One thing that is; It's) still astonishing is that so many researchers failed to include females in their studies. _________________(This is; A fact that's) especially strange when it comes to pain research. Women are the most common sufferers of pain and _________________ (but; yet) most basic pain research is carried out only on males. _________________(As a result; In many areas), there seem to be more and more reports that the results of earlier research are actually only true for males, _________________ (therefore; thus) making the earlier researchers look rather foolish. _________________(However; Anyway), what's important is that researchers are _________________ (now; just) beginning to take women into account. We may well see medicines better suited to female physiology in the future. _________________(In a few decades’ time; Soon), women and men with the same illnesses could be treated in different ways. _________________(And this; This research) may apply to more than just the brain. _________________ (That's why; So) it's an exciting field to explore—and one that could make a real difference to people's lives.
