1 Preload. 2  Preload refers to the stretch on the sarcomeres just prior to initiation of contraction (systole). 3  The more blood there is in the chamber just prior to systole (i.e. at the end of diastole, termed end-diastole), the more the sarcomeres are stretched.
The Allman Brothers song Midnight Rider is basically the perfect motorcycle song. It was written by Duane Allman, who was ironically killed in a motorcycle accident. Geico is now using the song in an ad to promote motorcycle insurance. The new ad has the song playing while a man made of money rides a motorcycle around some lovely roads. Buzzfeed has pointed out that Duane Allman and the band's bassist, Berry Oakley, both perished in motorcycle accidents.
In another series of ads, a GEICO pitchman is played by actor Jerry Lambert in an extremely bland and understated way, parodying the stereotype of an insurance man, such as reading to a group of uninterested children from a book of fairy tales about insurance.
