No surprise to me that the Helsinki Airport is now using dogs to sniff out the virus.
“WHAT” you say, “we have all this technology. “Okay” I say, “but how about this technology with 4 legs and a tail?”
A dog needs to smell ONLY 10 molecules of Covid to instantly detect it and the high tech machine need 18,000 molecules and a few hours.
A dog has 220 million scent receptors. Their sense of smell is 10,000 times a human. They can sniff out substances diluted to one part per TRILLION. They can tell the difference between diseases from cancer to maleria. A high tech machine costs millions. A box of dog treats about $2.50 and that includes all the licks and tail wags for free. Wow talk about what we all need more of. DOGS. The most miraculous beings on earth.
