By using this website, you accept that *anonymous* data is being collected about your visit, for example what web browser you are using (e.g. Internet Explorer or FireFox). This information is used to improve visitors’ experience of the site.

From May 26th 2012, the law says that visitors must be informed about the cookies that a website sets when you visit it. Cookies are small text files which a website places on your device in order to improve your experience, for example by remembering your name between visits.

On this website, cookies will be set on your device if you perform any of the following actions:

• Use the Facebook ‘Like’ or Google ‘+1’ button.
• Comment on a post. This means that you will not need to fill in your details again next time.
• Click a link which leads to Amazon. This is so that I will make a small percentage of the product price if you purchase via my website. If you prefer to cut me out, you can search for the product directly on Amazon. The product price, naturally, will be the same to you either way.
