Actually, this tuning, known as "High Strung guitar" or "Nashville tuning", puts a lot less stress on the guitar, since you're using lighter strings. I have an old Yamaha strung this way. Keith Richards used to call it "putting a little Angel dust on this track". Ian Tamblyn loves this tuning and has an old high strung Harmony Sovereign. Paul Simon has a black Yamaha that's high strung as well. He plays this a lot.
