Reply to Can doctors tell when cancer is caused by something specific, such as smoking or chemicals? by [deleted]

Sort of. Over the long term, they can do retrospective research (not very good data but still data) and prospective studies. Retrospectively they can survey or see the data of every person who smokes, vapes, and does both. They can do the same prospectively. Then they can see what cancers are more prevalent in group 1 2 or 3. For example, smokers got cancer A 5x more, vapers got cancer B 3x more, and both smokers got cancer C 2x more you can conclude that cig cause more cancer A, vapes cause more cancer B, and so forth. It’s just time and data. Don’t forget causation isn’t always a direct correlation. The best example is ashtrays. People with ashtrays in their homes have much higher lung cancer rates - is it the ashtrays causing cancer? No it’s the smoking. So sometimes you have to step back and ask if there is truly a direct causation between what you are studying and the outcome

Reply to What is a neurotransmitter "turnover rate", with reference to acetylcholine? What does it mean if the turnover rate is increased or decreased? by yungPH

Think of neurotransmitters (NT) as a person, and the synapse/neuron as a button. Imagine there are a group of people whose job is to press the buttons (stimulate the neurons) as many times and as often as possible but they get tired and leave. So turnover rate means how often the person gets tired and leaves the button alone. SSRIs do not allow serotonin to be “reuptaken” or in this example, the person in the room pushing buttons isn’t allowed to leave so he’s constantly pushing the buttons (stimulating the receptor). That’s a basic overview. Obviously overstimulation means your body down regulates the receptor (less buttons to push), and the opposite happens when you take something away from the body - your body upregulates the receptor - puts more buttons hoping to find a neurotransmitter (person) to stimulate it (push the button). Sorry if this sucks, hope it helps.

Fascinating. As a doctor for 15 years, I’m going to disagree with you here. Someone exhausted and feeling broken down at age 48 otherwise healthy as we know, the chances of dropping dead are less than 0.1%. Check the mortality statistics in this age group. However I’m sure their autopsy will be honest and accurate /s fuck Qatar

Reply to comment by Gryioup in If each side of our body is controlled by the opposite brain hemisphere, how do we blink in sync? by killians1978

Yeah it was eye opening learning about human physiology in medical school, only to learn why we know what happens to the body under extreme cold, heat, stress, etc. if you get really bored, read up on the Civil war experiments about the acid in your stomach and the soldier who got paid for it. There is no right answer - PETA is against mice experiments, human Guinea pigs are horrible, even volunteer humans who knowingly accept the risks are viewed as unethical clinical experiments.
