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.
Words Per Minute. In a speed test for typing, every five characters or keystrokes, including spaces, is classed as one word. Speed tests can be taken online on various different websites that enable users to type random passages of text in a set amount of time to determine their typing speed. This is given in wpm (words per minute), with deductions made for each word spelt incorrectly. Therefore, someone who typed 60 words of the passage in one minute and made 4 errors would have a typing speed of 56 wpm.
