I've noticed a decreasing of health in some villagers -- namely the researchers! And these villagers are in their 20s (1st generation). Is there a reason why? (I'm running v1.1 on Sony Clie, on fast mode when not paused.)

One researcher's health is dropping rather alarmingly. I am putting him on farming, hoping to recover some of his health

That should work. I guess all the exercise and fresh air is healthier than being at the research table, with it's occupational hazards, all day. I'm under the impression that farming is actually healthier than healing.
