No bias on this. Common sense. The long days of caring for that farm and the energy and determination to do it right is probably the reason John said younger. This is not a hobby or job for the older folks or someone who is a city person. Its hard physical work. Also take into the fact of severe Interior winter weather and daily feeding of animals, hauling supplies and feed in -50 temps for nine months, chasing off predators. But, the biggest problem is making it work to support a living. It could become a money pit.  Its no fun and games. You have to love the lifestyle. Hope some drug lord doesn't get it for his cartel manufacturing. Wish I had had a chance at something like this when I came here 40 years ago. It would be a bit of heaven.
