Will lighter strings extend an acoustic guitar's life?
I just sold an old acoustic I acquired in bad condition and restrung with new nut and saddle, whose bridge was beginning to lift out of the body. I traded it in for a different guitar whose bridge I checked is not lifting.
The new guitar has a set of .10 gauge steel strings on it - unusually light for an acoustic. This got me thinking, if the string gauge and thus tension is lower, would this help avoid pulling the bridge out?
Here's a bonus part of the question, the converse of the title. I normally use .12s on an acoustic, would changing this guitar from .10 to a heavier set, say .11 or .12, be likely to reduce its lifespan? I understand it would probably need a truss adjustment after changing size but even after that how would my working life be affected?
A good answer would probably cite material from luthiers or manufacturers as well as giving from personal experience.
Addition: (Following Scott's answer): The guitar in question is a Yamaha F-310, which is a dreadnought with spruce top, Meranti B&S, all laminate, Nato neck, Rosewood board and bridge. The bridge is quite wide and the guitar has a reputation for having brittle wood.
