    One other, very practical thing that makes Bauer's book outdated is
    his modeling of half-moon reading glasses with one lens removed.
    (And doesn't he look unhappy posing for that shot. :)  That was the
    courage of one's convictions)!  Reading glasses are necessary for a
    lot of us old fogies who are presbyoptic to read the sextant scale
    and record the numbers.  Now, you can buy inexpensive reading glasses
    with welded or soldered nose pieces rather than the plastic frame
    molded to fit a nose.  These can ride far down on the nose, leaving
    room to look through the sextant above.  I might add that reading
    glasses with a spring to close the earpieces also conveniently hang
    from a shirt more reliably than those without.
