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.
The Fastest Typing Speed. The highest typing speed ever recorded was 216 words per minute (wpm), set by Stella Pajunas in 1946, using an IBM electric typewriter. Currently, the fastest English language typist is Barbara Blackburn, who reached a peak typing speed of 212 wpm during a test in 2005, using a Dvorak simplified keyboard. The average wpm speed is only 41.4 words in one minute.
