    As someone else pointed out, x-lax gives you “smooth movements.” they had an advertising campaign in I think the 1980s. The slogan was “smooth move x-lax,” and it entered the vernacular slang for a decade or so. Generally, it was used in a sarcastic way when somebody does something that is specifically not smooth.

    It’s used as the punchline here because it is intentionality so cringeworthy.








  • That’s pretty interesting. I’ve done some genotyping before, and I’m guessing that they probably check a handful of distinctive genes, not the entire genome.

    For example, if they checked 45 binary markers (e.g. positive or negative) that would get you into that ballpark (assuming that they are evenly distributed and not correlated). Of course, there are also markers that are not binary but can have many different variations other than positive and negative.





  • The question isn’t whether it’s large. The question is how large is it? Right now the human population doubles every 40 years and that rate seems to be increasing.

    If humans somehow expanded in population and efficiently consumed all of the energy in the universe, then that means maybe somewhere on the order of 10^65 possible people (according to some very bad napkin math just for the sake of argument).

    Are there that many unique combinations of human DNA, ignoring mutations which would change the species or have no impact on biology?


  • I’m also no scientitian. I believe any mutations would have to be within the existing genome or else it would no longer be a biologically modern human.

    Let’s add the additional stipulation that we are not adding any meaningless genes. I know that there are a lot of them, but I’m just curious about what the math would look like and if we even have the knowledge about the genome to know which gene variations are meaningful.

    I’m thinking of the doppelganger thought experiment. Am I really the only person like me that has ever lived or will ever live? Or is it statistically possible that another genetically identical version of me could exist within the timeline of the universe (as I mentioned, with a 50% probability or better)?
