My "hard drive" sometimes feels like it's nearing capacity also. If I could replace it with one of the newer Solid State drives the speed would improve, my response would be immediate.
But if I could do that I would no longer ponder questions to me. I still work at 66 and my co-workers love my wit and the pieces of life I share with them, albeit slowly.
Yep I'll keep that old hard drive, it serves me well.
