Ah GOOD Jolandet!!! I always also check their health meter ... it will let you know what they DON'T like to do if they are stressed the meter will go down, at which point I help them train in another skill. I also like to give them a choice

some do better than others in a particular skill, and it doesn't hurt to be "well-rounded". When my villagers get to elderly status, unless they are completely happy at what they are doing, I usually take the check mark off, in case they want to do something different.
ALSO ... in real life, healing is NOT JUST ON THE OUTSIDE ... or in the physical .... doing even everyday chores, relaxing on the beach, dancing, enjoying the pool, eating, getting a drink of water, etc. aids in healing the mind and spirit as well ... so PART of the healing is not just for others, BUT FOR THEMSELVES. They might not show it in the skill bar so much, but you might notice that usually their health bar is way up there!!!
Ever hear of the saying "Physician, HEAL THYSELF?" How about "All work and no play makes Jack a dull boy?" LOL
I guess it is just everyone's perspective on how they operate ... I practice holistic healing and see things from a slightly different view than most people who are workaholics, or always have to be DOING something busy. Relaxation is a PART of the healing process, to help us keep ourselves balanced. The creators of VV2 seem to be echoing real life to a certain degree, and all of these little "side tasks" are a part of everyday real living. Life isn't always ALL goal oriented. When you get to a certain level in the game, where all of the preprogrammed "tasks" have been met, all of the collections have been collected, all milestones and levels achieved, you have enough tech points to help fully outfit another five tribes to the max and the only thing you can use them for is giving your villagers new clothing, and they have enough food to last 100 years without any farming at full 115 villager capacity -- seeking your villagers well being and helping the doctors and lighting the fires could possibly become your primary concerns ... they do things on their own. It's also nice to see some events too.
