DIY is a very popular activity - especially amongst those of retirement age with more time on their hands. But power tools, essential to many basic home improvement tasks, are almost always designed without taking into account the physical impairments that can result from ageing.

As we grow older, our eyesight deteriorates, our strength decreases and our dexterity is reduced. Tools are usually designed for able bodied workmen and industrial processes - emphasis is placed on purpose rather than ease of use or aesthetic. In particular, power tools are designed for physically strong users, with no attention paid to the growing domestic market of older people.

The challenge is to explore ways in which manufacturers, retailers and designers can be persuaded to take the needs of the older consumer more seriously. Is the answer to produce a range of 'special needs' equipment or can the needs of older people be successfully written into the design brief of mainstream products?
