I must reluctantly agree with you. I wouldn't consider myself old, but I'm hardly a spring chicken either. On my last trip, I didn't bring any of my PRO lenses. I got good results with the 14-42 EZ, 14-150 Mk I, and 9-18. I also packed along my tiny Speedmaster 25mm f/0.95 and fisheye body cap lens. And I ended up using all lenses fairly equally!When I travel, I do not take my pro lenses. Too heavy and bulky, for this old man. For me, at my age and condition, travel requires a compromise to reduce weight and bulk.
My basic travel lenses are the Panasonic-Lumix 12-60 + Olympus 17/1.8, then optionally the Olympus 40-150R.
My last vacation, the Lumix 12-60 was on the camera 99+% of the time. The 17 and 40-150 were used less than a dozen times in total.
