My wife and I were looking for new toothbrushes about a year ago and I found two, top of the range Braun toothbrushes on sale at Amazon for £65 each instead of £275 or roughly $85 instead of $360. Lots of functions and bluetooth connectivity so we can download an app to our phones or iPads and the brush will tell us how well we brushed our teeth???

Since they were much better units than we could buy for a similar price locally, we bought them and they are indeed damned good at cleaning teeth. Haven't managed to Google anything yet with mine but who knows....................

It would appear that if you have the time to look through Amazon, you can indeed find bargains when you actually need them.

I use Ryobi 18 volt battery tools and most of them are between five and ten years old. Three years ago, one of my batteries from one of the older drills started failing so I looked at replacing it. I also looked at uprating the older batteries to lithium ion for the improved performance and life. Here in the UK, it was actually cheaper for me to buy a new drill with charger and two Lithium ion batteries than it was to buy the batteries by themselves. So I now have three spare unused new drills and chargers which I consider to be free gifts and I replaced six old batteries for; if I remember correctly: 80% of the cost of simply buying six new batteries. As you say about printers and ink, the money is in the batteries with all cordless tools.

Simple question from simple engineer. If Henry's had sent you a better quality camera than the one you ordered and paid for, would you have complained?
I understand that your existing lenses may or may not fit but let's say they all fit.

Because of my arthritis, I have used a Logitech, cordless track ball for the last six or seven years. It is obviously a bit bigger than a mouse but despite the size, it is much more convenient than a mouse and being wireless means it can be placed in the most comfortable position to suit where and how I sit at my computer. Yes, they are a lot more expensive than a computer mouse but I think that they are well worth the price. I also use a Space Navigator when I am working on Autocad and architectural drawings.

Interestly, as a Scot who has travelled through / across America a few times, I scored 9 out of 10 so I presume that the questions were really easy.

Why does the article say, "President Bill Clinton"? Surely it should say EX President?

You young folks have all the fun.

That is the thing about humour. Not a lot is new, it is mostly recycled and updated to suit modern trends. :-)

My wife has a Fitbit Charge which she wears on her non dominant wrist. It records her steps, her heart beat, her sleep times and something else that I can't remember. Because of her arthritis, she is not very mobile so the step count should be quite low. However, she knits. Cardigans, socks, gloves, scarves, hats, non stop when she is sitting watching TV and the movement of her arm while she is knitting is recorded as steps so according to the Fitbit dashboard, she is an Olympic athlete.

I think that this is wishful thinking. Britain and Ireland are stuck in a position where the cost of anything that we actually need; be it fuel to get to work with or to heat our homes; is always as high as it can be because profits must be made by the Big Corporations and our government has so many ties to these corporations that it will not do anything to reduce the cost of utilities in this country. For example, our government signed up to the global agreement to reduce climate change and at the same time reduced or stopped the incentives to install solar panels and pursue wind and wave generated power sources while pushing ahead with carbon based fuel sources such as fracking and Chinese development of nuclear power plants on British soil. Iran is now allowed to supply the open market with oil and the general thoughts are that half a million barrels a day from Iran will be added to general production and theoretically, this should bring the cost of oil down even further. However, I very much doubt if we will see any reduction in the cost of petrol (gas) at the pumps in this country or Ireland.

You should see the prices for Macs over here in the UK. Astronomical.

You can also turn a sexton on it's side and use it for setting out (stake out). I have used one this way to lay out a line of buoys to mark spots for drilling close to the shore when my total station packed in.

Thank you for posting this one Graham, it is extremely interesting.

Thanks Jerry, I am a foot too short and have never been normal in my life. However, if you had posted this eighteen months ago, I would have had to have been seven foot eight inches tall to scrape into the normal BMI range. :-)

Unfortunately, in the UK, we are denied the "Right to Carry Arms."
