Comment Re:Correlation is not Causation (Score 2) 324

It all depends on lactase persistence and that depends on genetics. The relevant mutation in the gene for lactase is relatively new, without it you simply can't handle lactose after puberty.
The mutation is common in people with Caucasian ancestry, in purely non-Caucasian ancestry lactose intolerance is extremely common. If 90% of your adult population gets the runs from lactose then cows milk isn't going to appear in the national cuisine, except for maybe as a drink for children.
It is an interesting gene to trace because it isn't old enough to have spread over the globe yet.

A good manual saves 80% of helpdesk time. A really good manual saves 90%.
Ikea manuals are really good. They even allow their products to be less logical in construction, resulting in lower production cost and lower transport cost on top of the lower helpdesk cost. The manual is a one time investment, the others are continuous.
As with all things, this is a balance. Making a good manual costs time and money. I wouldn't be surprised if each IKEA product is assembled according to the manual a few dozen times before it lands in the warehouses, in addition to the time spend on writing, drawing and revising the manual. Ikea can recoup that cost as savings amortized over many many products, but not all products have such a large userbase that the invested time and money will be returned.
