Memory foam may seem like a brand new product to most people, but in fact it has been obtainable commercially for over forty years. From the early days until fairly recently it was mainly obtainable in the guise of mattresses, pillows, cushions and the type of padding that you get on doctors’ couches and wheel chairs. It was very costly, so it was not thought to be commercially viable for the mass market.
Nearly all people spend a third of their lives in bed. Everybody knows that. Eight hours at work, eight hours ‘at play’ and eight hours sleeping. We even say: ‘I have to get my eight hours beauty sleep’. I understand that some can do with less and that children, especially teenagers, it seems, need more. So, it makes sense to spend those eight hours a day, or night, as comfortably as possible, does it not?
Memory foam has been around since it was developed in 1966, but it has only been generally accessible for about twenty years, although twenty years ago hardly anyone could afford it.

The problem with the early foam was that it was too brittle, so it crumbled within a couple of years.
How many facts are there to be known or learned about all the objects and phenomenon in our entire universe? Just think: there are about 1 x 10 ^22 stars in the universe, that’s 10,000,000,000,000,000,000,000 stars; then there are many of those stars that have planets in orbit around them. Then consider the moons that orbit those planets and the comets and asteroids, the galaxies these stars form, the nebulae and black holes and everything else that’s out there. The amount of information and data is really quite mind-boggling. This article definitely will not contain every fact about astronomy, but they are very interesting facts nevertheless.
