In 2014, scientists started a 500-year experiment to determine the longevity of bacteria.
The experiment consists of 800 glass vials containing either Chroococcidiopsis or Bacillus subtilis that has been hermetically sealed with a flame.

For the 500-year experiment to succeed, scientists are supposed to test the dried bacteria for viability and DNA damage every other year for the first 24 years and then every quarter-century for the next 475.
The team left a USB stick with instructions as well as a hard copy on paper. As neither is foolproof, the team asks that researchers will at each 25-year point copy the instructions, so they remain linguistically and technologically up to date.

Current achievements provide happiness, but the memory of past accomplishments do not appear to produce long-lasting happiness.
The waning of ability in people of high accomplishment is particularly difficult psychologically. Retired athletes struggle profoundly after their sports career ends. They are prone to depression, addiction, or suicide.

His destiny is to die of bitterness or to search for more success in other careers and to go on living from success to success until he falls dead. In this case, there will not be life after success."

Unlike margarine or soymilk, cultured meat is biochemically identical to the substance it's competing with.
The USDA (responsible for overseeing agriculture) and the FDA (regulating drugs and dietary supplements) both could have some say in how lab-grown meat is labeled.

Our existence is invaded by science and technology as never before. For many of us, this brings comfort and rewards, but this existence is also more complicated and sometimes agitated.
Our lives are full of real and imaginary risks, and distinguishing between them isn’t easy. We have to be able to decide what to believe and how to act on that.
“Science is not a body of facts. Science is a method for deciding whether what we choose to believe has a basis in the laws of nature or not.”
