I brush it off because I've been lied to by these "experts" and "studies" my whole entire life. They've lied about climate change, they've lied about recycling, they've lied about what "causes" cancer, they've lied about what I should eat and drink....I can't think of a single aspect of life that they haven't lied about that was later reversed or declared false (which may be another lie).
And then the #metoo crowd muddles things even more.
So...meh. I'll just live my life and it will be fine because so far it has been. The majority of adults 40+ in this country grew up with parents smoking their asses off in the car with rolled up windows and no seatbelt, let alone car seat. We ate bologna sandwiches on white bread for lunch and Capt. Crunch for breakfast. We ate Banquet TV dinners and pot pies. We rode our bikes without helmets and played outside wherever we wanted until the street lights came on. And we're fine.
