Hand Over Hand

You can't hold up your books with your hands all day. Or can you? If you can, do, or any combination of can and do, I have two questions for you:

1) How strong are your arms??? Damn. The endurance you must have.

2) Do you have a job or friends or anything like that that would require abandoning your station at the bookcase?

If you had these bookends that look like hands, maybe you wouldn't be such a sad person with your big arms and shoulder discomfort and sleep deprivation.
