how can you take care of them? and whats the life expectance of them (years etc)?

I'm not sure as to the life expectancy, but I do know stores such as Wilsons Leathers and other stores that carry leather products generally have some sense of a spray you can use to preserve the life/quality of leather goods.

They can last a lifetime if taken care of well. It also depends on how often you wear them. Wearing them everyday they will definitely not last a lifetime of course. Usually you can get leather sprays and polishing cloths at the retailers.
