Re: What are these white dots on a lunar photo?

Yup, people don't realize how dangerous human touch is to certain 
materials.  We're slightly acidic(?) so anything we touch is going to 
get a dose of etching acid, and then the disintegration sets in.

So during the holidays, be careful of that handshake or your palm may 
melt away, or that hug lest your clothing disintegrate, or heaven 
forbid, kissing; God Knows what bugs are sitting there patiently on that 
person's lips, just waiting for the next ride to hitch on to come by.  (^_^)
