I have another question. One of my female villagers, has really good stats, always has bad health. She's not sick but weakened all the time. At times the red goes back to being yellow (or was it orange?), and back to red again. Now I'm noticing her health is extremely low. Some side notes she's 58 now and has had maybe 6 kids?

(They/She had a field day while I was asleep)

Is there any way to make her health better? Or avoid this situation with my other females?
