Like taking an extra hour to make a really good dinner. That, in my opinion, is an essential part of life. :-)
Also, check out the sweet experiment I got to be around for.
Using a CT machine and testing a brand new probe from Radcal that was amazing if I do say so (event though I'm still brand new to the field...). Anyways, this was totally a highlight picture. We did tons of cool stuff with it.
