I also agree, but have a question:  I have noticed that the quality of the
snot-ball will foretell the how well the DNA will sequence:  If the
snot-ball is really sticky the dna sequences well, if it is pasty rather
than snotty, it doesn't.  (Thats why I tootpick it out rather than pouring
the sup off). Any ideas about why this happens?
