comment Why are antibiotics prescribed with a viral infection like a cold?
You're missing the point, and clearly you have some agenda to make. I agreed that doctors can mis-prescribe, or even err on the side of caution to prescribe, antibiotics. It takes a long time to assess whether common infections are bacterial or viral because they have to wait for strains to grow or viruses to be immunoassayed. You seem to be taking a lot of "facts" completely out of context. For instance, 7000 deaths/year, where? The USA? So that is 0.002% of the population, or several of orders of magnitude smaller consider the number of hospital visits.

comment Why are antibiotics prescribed with a viral infection like a cold?
"Well you said "medication errors in hospitals" which is ambiguous. To which classes of medications does that statistic refer? It's not at all clear it applies to antibiotics. And it applied to hospital prescriptions. It's fair to say most people get antibiotic prescriptions from family/general physicians and thus outside of a hospital setting. Lastly, antibiotics are generally not a fatal medication, so how would a death occur? Perhaps the patient was severely allergic and had a reaction, or, perhaps they received a totally different drug than the antibiotic they were meant to, then died.

comment Why are antibiotics prescribed with a viral infection like a cold?
You're general sentiment is correct. However, it does not address the reality of how doctors end up prescribing the antibiotics in any case. The main reasons come down to: viral and bacterial infections may look similar in early stages and so it is prophylactic; patients can be "demanding" and get a prescription before leaving the office; and some doctors may use poor judgement. Prescribing a placebo is unethical when the potential for harm can be real (what if a patient is immunocompromised?). Lastly, the 7000 deaths/year is not specific to antibiotics and is an irrelevant statistic to cite.

What is the purpose for (ostensibly) a breast model? These are commonly used in radiotherapy models but I am not familiar enough to point you to a data source.

comment Is there differences in components of saliva among species
Some functions stay the same. For instance, at least in mammals, saliva helps to lubricate food for swallowing, begins digestion of starches by amylases and provides a liquid medium in order for taste sensation to funciton. More broadly conserved in animals is the inclusion of antimicrobial peptides in the saliva that function as a primitive immune function to keep the oral cavity clear of harmful microbes.

Not to nitpick, but venom is technically injected and is not a normal component of saliva. Toxins on the other hand are completely normal.

comment Why aren't we allowed to refreeze previously thawed breastmilk in refrigerator?
Something to note is that the thaw and refreeze cycle is not just about texture, but there is real damage happening to the proteins that are present in the milk. All the good things that make breast milk useful for infants (growth factors, hormones, antibodies, etc) will be destroyed by freeze-thaws.
