Explanation:
The current model of a perfect body is one that is thin and fit. This image is shown on advertisements, movie and TV stars, and most viral videos.
The current fad has not always been the case. For much of history, and in other cultures right now, more shapely curves are thought of as normal and desirable. Even today, there is a range of what people like and do not like in terms of the shape of a body.
A person that does not fit this image may feel bad about their own body, unless they develop courage to just be themselves.

Explanation:
Prions are the infectious particle composed of harmless proteins found in the brain of the animals like humans, cows which are responsible for the degeneration of the nervous tissues of the brain.
These proteins of the prions are resistant to the enzymatic actions and thus they can multiply and accumulate within the neurons and destroys them forming holes in the neurons giving the sponge-like appearance and thus disease is known as transmissible spongiform encephalopathies.
An example of this disease is mad cow disease which spreads from the cow to human by eating the meat of the cow especially brain contaminated with prions which are neither considered viruses nor cells.
