I do prefer his earlier and more unconventional works, between around 1965 and 1975. He has composed the music for over 500 films, and I read somewhere that it was because the budgets were often so low that he was forced to rely on such unusual instrumentation as whistling, Jew's harp, surf guitar, and the unique wordless vocal stylings of Edda Dell'Orso, whose collections are out of print and too damn expensive, although I was lucky enough to pick up a used copy of the first for under ten bucks. Woo hoo!
I also recommend the cult film Seconds, which is all about diabolical freedom. Imagine if you could incarnate yourself. What could go wrong?
As for magical cures, brain elixirs, and life extension tweaks, I recommend the company Bulk Supplements. I'm experimenting with several, and before today, they seemed to be helping.
