I don't really mind. I do have some very light guitars, like my St. Vincents, my Vox Bobcats, and my Thinline Teles. But my Gretsch 5622Ts are in the 9 1/2-10 lb range, and it's never bothered me.
I come from odd stock, though. One late grandfather was a janitor well into his 60s. The other owned a small grocery store and was nearly 50 when my late father was born. 6'5" (despite being born into a poor village in Greece in 1895), lean, and very strong. He was observed into his late 60s taking stairs up from the storage cellar 2 at a time with a 50 pound potato sack over each shoulder. Never had a back issue. So I count myself lucky. I can absolutely see why some people care a lot about weight.
