In Space, NASA is searching for ways to stop people from getting bad health because of space travel. Apparently being in space is very unhealthy. The lack of gravity causes bones and muscles to waste away and every part of the body is weakened by microgravity. Fluids are forced up to the head because we're designed to resist gravity.
I think that is the main reason the International Space Station exists. The ISS is trying to find ways to keep astronauts healthy for long periods in space. I remember reading of some other experiments they were trying, they wanted to see how certain crystals grow in the absence of gravity.
The pictures of crews always seem awkward like they're trying to keep themselves steady. It's not just NASA that is searching for something. Down here on earth, ordinary people like myself are always searching for deals. I search for short break deals, deals on used electric cars and deals on ordinary items.
I look through all the places we can go and the hotel tariffs and see if they change for different dates and places. Then I remember places I have already been.
I think if you had an electric car you would want to change your energy tariff so there is a time window when the electricity is cheaper so you can charge up your car without spending too much money. Perhaps there would be a 5 hour time window when your electricity is only 10 p per kilowatt-hour and it would be cheaper to heat your house with electric heaters during that time.
I'm just amazed how quickly electric cars devalue over a short time, car gaint was selling fairly new cars for about one third of their original price. I was just looking at them the other day.
