Couple points. One of the best things about this conversation is what my maumau would say, "Don't throw out the baby with the bathwater." Sound scientific method is not binary (and nature rarely is). Equally baffled why that same maumau knew to tell my mother to use a tissue or elbow during cough/sneeze yet public health officials didn't get it. Loving memories of my mother slapping my arm "Cover your mouth!" New K-N95 is always in my purse, but I rarely use it without cause these days

This Supreme Court terrifies me. Even women's most modest reproductive rights trampled from complaint suits brought about in strategically selected geographical courts on the FDA is a very good example. p.s. Raised my kid in parks, wild local green space, and LIBRARIES... from using conference space to help fellow nursing mothers to family Thurs at the planetarium. We have to stop banning books placed in appropriate sections. Erosion of basic human rights is happening at warp speed.

I'd like to know where Drumph gets his numbers. he says a couple of million illegal migrants have come into the USA from Canada. He should be trying to stop guns from coming into Canada from the USA. That's a real problem. we have had 3 murders in the last year. that's more than since 1966 when my town started. He also said that Canada is responsible for 200000 or 300000 people because of the opioid crisis. he is a whackjob and he is speaking language that sounds like a preemptive strike speech.

I love a good mashup - just like 99PI and Brandon Lee Mulligan, or Robert Moses and D&D. These crossovers make me feel more connected to the world around me, somehow.

Loved this perspective on the Brooklyn Bridge- it always amazes me to remember both the ingenuity and the sacrifice that built such incredible structures in times before our most modern machines.
