You would think that the chickenpox virus being airborn would mean “little drops of spit in the air” since that’s how most viruses do it. Alas. That is not how chickenpox goes airborn 😬

No evidence that medicinal cannabis effectively treats anxiety, depression, or PTSD - according to the largest review of cannabinoids ever conducted.
Researchers using Saccharomyces cerevisiae showed that replicative senescence is triggered when a single shortest telomere falls below a critical length, which both initiates senescence and promotes genomic instability that can transiently enable cells to escape it. 🧬 https://t.co/TOUeXB4L3v

Elastic tissues aren't isolated; they're part of a messy, damped, energy-leaking body. What they do is store a chunk of it temporarily as stretch, twist, or shear then dump it back out as recoil.
