I agree DC2. I think a lot of people don't know much about microbes and human existence. There is an interesting TEDx lecture given on the subject of 'Are We Too Clean?' by Claire M. Fraser. Here's what is said about her:
"Claire M. Fraser, PhD, is a world-renowned scientist who launched a new field of study microbial genomics and,
through her ground-breaking research and pioneering leadership in this field, has fundamentally changed our understanding of the diversity and evolution of microbial life on Earth."
A couple of highlights for me:
A little after 2:00 in the video; there are about 10 times the number of microbial cells in the human body than human cells. They weigh in at between 3-5 pounds and would almost fill a gallon jug. Without them we would die.
A bit after 14:50; Talk about the 'ick' factor, she talks about fecal transplant to restore human GI microbes that were decimated from antibiotic use.
Here's the video:
I'm not worried about microbes on my drip tip even if I never clean it. A dirty drip tip is 'cleaner' than my mouth is 99% of the time.
Now, I'm not saying it's a good idea to go out and play in animal droppings or to eat uncooked chicken, but IMO our society is too clean today and I feel no desire to join in. It's unhealthy
