In older people, aortic dissection often results from high blood pressure. The high pressure can cause part of the aorta's wall to deteriorate. Aging itself can cause similar deterioration.
When was jazz founded? Jazz wasn't founded; it evolved from and incorporated various sources (including Spanish military band music, Ragtime, an early form of what is now called blues, and boogie-woâ¦ogie) especially in New Orleans between 1895 and 1915.
Jazz meaning short, free improvised passage performed by the whole band dates from 1929, and yielded jam session (1933); but this is perhaps from jam (n.1) in sense of something sweet, something excellent.
