Summary:
In this chapter, Keane talks about the NASA tragedy in 1981. He mainly talks about how nitrogen is a silent, but deadly killer. Nitrogen has no scent of color so it is very hard to detect, but when inhaled will shut down your brain. Keane also explains that almost any gas, including nitrogen can trick your body into inhaling it thinking that its oxygen. Keane talks about how titanium started being used for implants rather than wood. Titanium helped was a better choice because it did not cause any infections and tende to attach very easily. It began being used rather than wood in the 1950's. Keane then moves onto the elements and taste.
He discusses how the elements can trick your taste buds into thinking that it is a sweet food that you are consuming rather than a harmful element. Keane gives the statistic of how many people in the world have what is called acute Beryllium disease which is similar to a peanut allergy. The statistic is one tenth of the human population has acute beryllium disease. He next begins to discuss Gandhi and his salt march and how iodized salt is better for you. Iodized salt is a lot better for people because iodine is only needed in small quantities The Gandhi march involved that India did not like iodized salt because they weren't too fond of Western sciences.
Reflection:
This chapter was a rollercoaster of new things that i was not aware of. Carbon monoxide is common knowledge since we have detecting alarms in our households to prevent such a thing from harming us. I found it surprising to know that common salt isn't as good for us as iodized salt and how India did not find our studies believable in a sense.
