So, a resting pulse rate for 79 is perfectly normal. Conditioned athletes might have a much lower resting pulse rate. 100bmp and higher is considered tachycardia, although for some people, this could just be normal.
A. One space after a colon. There is a traditional American typing practice, favored by some, of leaving two spaces after colons and periods. This practice is discouraged by the University of Chicago Press, especially for formally published works and the manuscripts from which they are published.
I was taught it was two. A good way to remember this is by counting the dots on it. The colon has two so it has two spaces. A semi colon has only one dot, and it has only one space after it. But this only applies when the name of the punctuation has the word colon in it, as when you are counting the dots in a period, you only see one, but after a period, you usually put two spaces unless you are using a wesite address or something of that sort.
