Appendicitis occurs when the appendix becomes blocked, often by stool, a foreign body, or cancer. Blockage may also occur from infection, since the appendix swells in response to any infection in the body.
A familial generation is a group of living beings constituting a single step in the line of descent from an ancestor. In developed nations the average familial generation length is in the high 20s and has even reached 30 years in some nations.
Numbers 32:11-13 may reckon a generation as 60 years, including people 20 and above and giving them 40 more years to live. One may interpret this to mean a generation is the 40 years of adulthood between the ages of 20 and 60. Job lived 140 years and saw four generations (Job 42:16). This would make a generation about 35 years. Basically, generation is not a specific number of years but a more or less specific period of time.
