A dotFIT answered. The half-life, which is the time required by the body to metabolize or inactivate 1/2 of a substance activity, for caffeine (doses lower than 4.50mg/lb) ranges from 2.5 to 10hrs. Meaning, caffeine has little to no pharmacological effect after this time but may still be present in small amounts in the body.

The post office moved to Brewster in September 1884, then back to Ladora in May 1887. In January 1888 it was moved again to the Brewster location and the buildings at Ladora were either moved or torn down. The reason for these changes are reflected in a unique county seat fight. In organizing the county, an election was to be held in Brewster on November 6, 1886, to vote for the county seat. In that vote, Ladora got 63 votes, Blaine Center 43, and Brewster 24.
