Darn tootin, StephN -- take a good break -- from the Herceptin! And get out there and get every bit of sunshine and make up for the northern clouds:

One of the most interesting things about sunshine is that it works on the pineal gland to produce the tryptamines, like melatonin, which in itself seems to offer some protections against cancers...
 
Take 
everything off, go soak up the sun, and enjoy being alive!
 
Naturally,
