I don’t think so.
And since I have only one good hand in operation my time, extra or not, is somewhat limited in its disposal. The time I will take to type up this blog posting will use any temporal overage I may have. When I am at the keyboard my fingers (all five of them) are flying across the keys at a blistering 5 – 6 words per minute. That apocryphal group of typing chimpanzees is faster than me and often more creative.
