My cerebral cortex, the gray matter that MIT neuroscientist Steven Pinker likens to 'a large sheet of two-dimensional tissue that has been wadded up to fit inside the spherical skull,' is riddled instead of whole.
Dementia is, after all, a symptom of organic brain damage. It is a condition, a disorder of the central nervous system, brought about in my case by a viral assault on brain tissue. When the assault wiped out certain intellectual processes, it also affected emotional processes.
Enzymes catalyze all the reactions of life. They're what allow you to extract materials and energy from your environment and turn that into muscle and tissue and fat. That's all done by enzymes. They're pretty remarkable chemists - they're even better than Caltech chemists.
Carbon pollution contributes to climate change, which causes temperatures to rise. Hotter temperatures mean more smog in the air, and breathing smog can inflame deep lung tissue. Repeated inflammation over time can permanently scar lung tissue, even in low concentrations.
Your cells are not working as hard as your dog's but harder than your horse's. The bigger the animal, the less energy needed to sustain a gram of tissue.
Scar tissue is stronger than regular tissue. Realize the strength, move on.
I had a few fibroids removed, and they left me with a Grand Canyon of scar tissue in my uterus. The doctors weren't sure I'd be able to reproduce. I was prepared for a rough road, and then out of nowhere we conceived.
If I do hit that rope and do a hop, skip and a jump and get up as high as I can, I'm just going to hold my breath, because I know i'm going to hear all kinds of scar tissue popping.
At birth, we are like cartilage - soft, flexible tissue. By the same natural process by which cartilage becomes hard bone, the soft, tender heart of an innocent child can become hardened by the circumstances into which she is born.
I did help to set up an undergraduate course in medicinal chemistry and made progress in modelling and analysing pharmacological activity at the tissue level, my new passion.
