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 live 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 electrolysis(电解) based on a source of 100% renewable energy.Several producers have turned to producing Re-Hydro,mainly because of lower tax,which also keeps the price of Re-Hydro on the same level as regular hydrogen.Most analysts believe that Re-Hydro will be the dominating fuel in the future.
