In some instances it's possible to design a small system without knowing your flow. However, we don't recommend this! If you don't know your flow you can easily design a system that puts out more water than you have available. The end result is a system that doesn't work and that gives you more stress than doing your taxes on April 14th. Sometimes you can have a small system that works for years suddenly stop working if you add on in a way that exceeds your flow.

For some women, there will be no warning — their periods will simply stop. But most will go through a phase of erratic periods before they reach menopause. Periods will get further apart, or occasionally closer together. This phase is called the 'menopausal transition', or 'perimenopause', and it can last for several years.

Kyoto is Japan's primary tourist destination and has the infrastructure in place to make your stay enjoyable and stress-free. Subway and train station signs are clearly marked not only in Japanese but also in English, Chinese and Korean for easy comprehension. Buses post their destinations in English and Japanese, and stops are announced in English as well on board making it even easier for the visitor to navigate the city.

Strictly speaking, "spy-ware" is computer software that gathers information about a computer user without the user's knowledge or informed consent, and then transmits this information to an organisation that expects to be able to profit from it in some way. Data-collecting programs installed with the user's knowledge are not, technically speaking, spy-ware, if the user fully understands what data is being collected and with whom it is being shared.

Tell-tale signs of Spyware presence are computer slowdown, pop-up ads, erratic mouse behaviour, and problems with a Web browser-like browser instability, strange homepages and confusing search results. To determine if your computer is infected with Spyware, you will need to download a Spyware detection tool. Most respected anti-spyware companies offer a free scan or free trial version of their software.
