Have you ever wondered why your hair becomes frizzier and curlier in humid weather? The answer to the question above is humidity. Apparently, chemical makeup of human hair is very sensitive to ambient hydrogen. So sensitive, in fact, some gadgets used to measure humidity -- called hygrometers -- rely on hair for their readings. 

So why does humidity make hair frizzy? When hydrogen bonds form between the proteins and water molecules in your hair, it will become curly and frizzy.

A growing number of people are making the decision to be cryogenically frozen after death in order to receive a second chance at life. Despite the fact that no method of revival from being cryogenically frozen exists to this day, these individuals are hoping that advances in future medicine and technology will allow them to be revived and cured of conditions that killed them.

Looking at current research, this topic is certainly controversial both in and out of the scientific world. Many scientists claim that cryonics is founded on false promises and unprovable nonsense. Whereas others claim that death and aging will be looked upon in the future as primitive and unnecessary experiences.

 Nevertheless, reading more about the people who have already endured the deep freeze is certainly interesting and slightly bizarre.

Five Cryonically Frozen People

1. James Bedford

Bedford, a psychology professor at the University of California, is the oldest cryogenically frozen human being on earth. He died on January 12, 1967 due to kidney cancer and became the first person to enter cryonic suspension. This was a huge milestone for the cryo-community and January 12^th is regarded amongst the community as “Bedford Day”.

2. Ted Williams

Williams, an American professional baseball player and member of the hall of fame, is currently the most famous cryogenically frozen person to this day. After dying of cardiac arrest, his original wishes to be cremated were overlooked as his son produced the controversial cocktail napkin on which Williams said he wanted to be preserved with his family.

Measles. Mumps. Smallpox. Polio. Diphtheria. Tetanus. Yellow Fever. Influenza. Hepatitis.

Imagine a world where all children of the present day commonly suffered from these diseases. The vast majority of them would be blind, deaf, or unable to live independent lives due to various disabilities resulting from these and other diseases. Great care would have to be taken in this hypothetical world to not get sick. And still that probably would not be enough to prevent illness.

The world would look vastly different.

Thankfully, these eliminated diseases are no longer a major concern in an ever-increasing share of our present world thanks to one of the most important inventions of all time: the vaccine.

People rely on vaccines to ensure that they will not have to endure many diseases or resulting disabilities in their lifetime. A bothersome scenario is a population that thinks it is receiving immunization, but is left further vulnerable to diseases. This is what happens when a population thinks it is being safe and a vaccine, that could have been either improperly stored or mishandled, is no longer effective.

Properly Storing Vaccines
Technology has had a huge impact on the effectiveness of vaccines. Thermometers have especially undergone the shift from consumer technology, simple digital home devices, to healthcare technology, information technologies used to enhance and optimize processes and improve care.
