LOL, stop it you two!! What if I dislike laughing!!!

These tips are good, and that is how I typically make elders early on in the game. But once I have a stable food source I will typically start all new workers on building for several reasons.

1. Teaching a villager to build is the hardest and most time consuming trade.
2. When the villagers are older it takes longer to do one cycle of building as compared to the others.

After they have mastered building I will then move them to farming. Again because there is a lot of walking to do to complete the task.

Then after they have mastered farming I put them at the table. If they are elderly they don't have to walk anyplace, so it seems to speed up the process up.
