Here is some news of the future.
March 20, 2035
There was a lot of news around the life extension drugs that hit the market a decade ago. They didn't promise that you would like forever, but they gave you a chance to extend your life an extra five to ten years. Even though the life expectancy rate at birth has increased greatly, the life expectancy for seniors hasn't improved that much. Basically, you have a greater chance to become a senior, but you will not have a much longer lifespan, and this is where the anti-aging drugs intend to kick in. So, do the anti-aging drugs work? Well，it is too early to tell. But the sales so far are very good.

Although introduced in the market only five years ago, 10% of all hydrogen fuel now sold in the US is of the environmentally friendly Re-Hydro label, produced through eletrolysis(电解) based on a source of 100% renewable energy.
