Posh Thoughts

Technology has really gone a long way. While it seemed that many are destroying the environment, today, when man invents, ample consideration for the betterment or the delay of destruction of the environment is always thought of. That is why picture tubed monitors (CRTs), which are harmful to the ozone layer, have been replaced by LCD and LED monitors.

It used to be that books have always been published and printed on paper, which is one of the causes of felled trees. Despite the recycling factor, the fact remains that the trees felled are no longer there to help give oxygen and suck up excess water to avoid flooding. To help, go for kobo ebooks instead.

What is the difference between standard wheels and casters? The ordinary wheels are attached to an object that is wheeled by way of a shaft through the center hole of the wheel, just like any land vehicles like cars, trucks and buses. When you change a wheel, you unscrew from the side and pull off the wheel sideways.

Casters, on the other hand, are built with an attached fork upwards which is what is attached to whatever it is that needed the wheels like a grocery cart, a computer swivel chair, or a hospital bed. A caster can be with or without a lock, can be rigid or swivel.
