So it seems to me that seeing a physical therapist, a massage therapist, or a kinesiology therapist would be a more effective way to find useful help than seeing a chiropractor. After all, none of the above people are going to try to treat your non-existent subluxations.
In baseball statistics, earned run average (ERA) is the mean of earned runs given up by a pitcher per nine innings pitched (i.e. the traditional length of a game).It is determined by dividing the number of earned runs allowed by the number of innings pitched and multiplying by nine.Runs resulting from defensive errors (including pitchers' defensive errors) are recorded as unearned runs and are not used to determine ERA.t is determined by dividing the number of earned runs allowed by the number of innings pitched and multiplying by nine.

An ERA is a long period of history with distinct characteristics. For example, the roman era. A PERIOD is less distinct and defined, it simply represents a portion of time, be it a very short portion, or a very long portion. For example, my period of sadness and the jurassic period. An EON is an actual unit of time. 1 eon = 1 billion years. This is also used rhetorically to symbolize a long long time. For example, man! my new iphone took like an eon to arrive in the mail! or also more appropriately the earth is 4.5 eons old.
