I am collieuk, a relative novice at Wikipedia editing. I am English born and an English resident, but I have lived about half of my 50+ years in the USA. My degrees are in physics, so banks consider me a low risk as a loan candidate, but actually I am a mathematical physicist, really a mathematician, so I should be considered a high risk candidate. Ha ha, banks. I mostly edit articles relating to my principal hobby, pure-bred dogs, and particularly canine genetics. I read Wikipedia quite widely, and if I see the need of a link, I put it in. Some times I may be a bit lax in putting in references, but I try to enter material which is true and not from my original research. If called on this for some specific incidence, I will find a reference. I will try to put some bells and whistles in this user page when I have the time and inclination.
