Tendon also have a role in the tensile properties of tendon. The structure of tendon is effectively a fibre composite material, built as a series of hierarchical levels. At each level of the hierarchy, the collagen units are bound together by either collagen crosslinks, or the proteoglycans, to create a structure highly resistant to tensile load. The elongation and the strain of the collagen fibrils alone have been shown to be much lower than the total elongation and strain of the entire tendon under the same amount of stress, demonstrating that the proteoglycan-rich matrix must also undergo deformation, and stiffening of
What Is Life the role of "entertainer" in his songwriting. In "I Me Mine", Harrison recalls that he changed his mind about offering "What Is Life" to Preston once he'd arrived at Olympic Studios and found the singer busy working on more typical material – or "playing his funky stuff" as Harrison puts it. Rather than attempt it with the Beatles during the band's concurrent "Abbey Road" sessions, he stockpiled the track with his many other unused songs from the period – "All Things Must Pass", "Let It Down", "I'd Have You Anytime" and "Run of the Mill" among them – and revisited
