Wemmie's studies have shown that these acid-sensing proteins are required for normal fear responses and for learning and memory in mice. However, while you can buy a kit to measure the acidity of your garden soil, there currently is no easy way to measure pH changes in the brain.
For the normal version of the english typing test we have calculated an average of 41 WPM, this value is based on over 73 million typing results. Considering that these words are relatively easy to type, the avg WPM is probably around 20-25 WPM for normal text with punctutations etc.
WPM, the number of. words typed in a one minute period of time, WPM = ( Words without errors + Words with errors. ) / Time spent. the average for worldwide is 50 to 80 wpm (averaged out for. manual and electric typewriters).
