This is your brain on Java:

Every profession has its share of workers who continue past their prime years of productivity. Maybe you've seen one...the overweight police officer who looks more at home in a Krispy Kreme shop than in his cruiser. I'm thinking software engineers have to "throw in the towel" sometime before 40...before the ol' brain loses too many working cells.

BottomFeeder and Silt, on the other hand, are from the over 40 mind of a Smalltalker. It doesn't have to be hard.... It only is because Gosling, Steele (et. al.) revel in pointless complexity - supposedly to make your life simpler...
