Frisky

Early humans were likely to have been more competitive and promiscuous than we are today.

That's the conclusion of a study that looked at the fossilised finger bones of extinct apes and hominins - extinct members of the human lineage.

The study showed they were exposed to higher levels of androgen hormones in the womb.

Exactly what that means I am unsure, but I believe the scientists.

The Lie

  The adage that if you tell a lie enough times, you believe it - never could I imagine it worked for the entirety of media, but it has.   Shame on you all. Biden when asked why he ran in 2020, stated (I am paraphrasing but the quote exists and you can find it) - I ran because of what Trump said about Charlottesville and KKK members being fine folks. CNN told that story, CBS retold it, NBC told it.  MSNBC told it.  ABC told it.  New York Times told it.  And it was a lie.  Lie.  Lie.  Do you understand the difference between braggadocio and lie, between self-inflating ones ego and a lie, between causing and creating harm to ones character and misleading people.  A lie is not what Trump told.  Trump tends to exaggerate... greatly.  The media lied to the American people and the world about Trumps comments concerning Charlottesville.   When Biden and many other political elite retold the lie, the media did not call t...

Spain downgraded, Europe debt crisis widens Juergen Baetz, Associated Press Writer Wednesday April 28, 2010, 12:39 pm EDT BERLIN (AP) -- Europe's debt crisis mushroomed Wednesday as Spain saw its credit rating lowered, just as Germany sought to reassure nervous investors that Greece would not be allowed to go under, saying Berlin's share of a key aid package could be approved in the next few days. Stock and bond markets had begun to regain their composure after stinging downgrades of Greece and Portugal the day before, when Standard & Poors delivered more bad news by cutting Spain's rating to AA from AA+ amid concerns about the country's growth prospects following the collapse of a construction bubble. "We now believe that the Spanish economy's shift away from credit-fuelled economic growth is likely to result in a more protracted period of sluggish activity than we previously assumed," Standard & Poor's credit analyst Marko Mrsnik said.

No time to stop and read the details! Just smokin'

      The following from Slate.com, Jacob Grier Feb 13, 2017.   A decade later, comprehensive smoking bans have proliferated globally. And now that the evidence has had time to accumulate, it’s also become clear that the extravagant promises made by anti-smoking groups—that implementing bans would bring about extraordinary improvements in cardiac health—never materialized. Newer, better studies with much larger sample sizes have found little to no correlation between smoking bans and short-term incidence of heart attacks, and certainly nothing remotely close to the 60 percent reduction that was claimed in Helena. The updated science debunks the alarmist fantasies that were used to sell smoking bans to the public, allowing for a more sober analysis suggesting that current restrictions on smoking are extreme from a risk-reduction standpoint.
