I have gained level 2 in all the techs and level 3 in farming, science and culture. I have about 70 population and about 4 adult doctors. I have 5 tribes in all and they all seem to be the doing the same. I have solved 9 puzzles in once of the tribes and around 6 to 8 in the other tribes. So I am quite a long way into it.

My strategy is to have roughly the same number of people doing the same types of job, so they have an even spread of skills. I have a spreadsheet recording who does what so that I can keep on track with them all. I change their jobs if I get impatient with a task and decide that I need loads of builders, then I change them back to their original jobs once a task is completed.

I don't want to reduce the number of doctors too much in case one of them suddenly dies and then I am stuck without an adept doctor when i need one for a puzzle or event that I haven't yet come across.

I might just have to be brave and change one tribe to only having one doctor and see if that works.

Thanks for answering and being really great at not giving me any spoilers. I just want to make sure I'm not being a doofus!

Thanks.
