If something didn't exist or was not very important one hundred and fifty years ago, it very likely isn't very important now.
My MediMania blog posts are about new fresh medical hysteria that swears common ailments with us for thousands of years are going to kill us all. Strangely, humanity survived in the past and we will likely survive now, in spite of expert medical opinion that nature has somehow changed.
Don't be fooled by hysterics who ignore the past. Humans can be quite resilient even if modern narcissists see society and people as incredibly frail.
