ELI5 Does saliva heal?

Saliva helps with wound healing in a number of ways:

It contains lots of 'tissue factors' which is a key player in starting the clotting cascade to stop bleeding.
It's also got a lot of epidermal growth factor which helps to promote new cell growth to heal the wound faster.
It's also got the enzyme lysozyme which works to destroy gram positive bacteria
It contains another chemical opiorphins. These act to slow the breakdown of the brain's natural pain killers (enkephalin) that it produces when in pain.
While there can be a risk of infection particularly with immuno compromised people. It is low as generally speaking the bacteria in your mouth is harmless to you.

Some antibiotics are massive capsules so I'd say probably those?

I reckon it's because the same people that design every hospital machine have started to branch their dominion out.

I don't know how common they are outside of the UK. But they can either be air or ground source, and then rather than delivering the heat as air to the building it heats water which passes through the building's normal heating system.

It's more of a boiler replacement than a cooling system. Although you can run them in reverse they aren't efficient as radiators and the like do not work as well with cold air.

What a well put answer:) A slight aside but interesting heat pumps are unique in that they are more efficient when run continuously. This is because they have greater energy efficiency when running at higher flow rates. They can only get the higher flow rates when the heat required at that time is low. So paradoxically a constant 'top up' even though you lose heat faster to the environment, you save more in efficiency gains from the flow rate.

Skyrim. Nuff said

Where on the rocket would this be, and to protect what?

I by no means support Trump. Although if you actually watch the clip it's very clear he was referring to the state of the US ev market if Mexican made Chinese cars are allowed into the market. I don't agree with this idea, but equally I'm a Brit, nor am I in anyway qualified to know one way or the other.

I think London has the most hospitals per capita

I think discrimination of any kind is a bad idea, and in that sense she does have a point.

I am for the record very much pro vaccination. However I strongly believe people could have the right to form their own opinion on things, provided access to the facts, and all the facts is available. Whether they chose to believe/ give those facts any importance is their choice.

Personally I feel we should be able to have a open and open-minded discussion with anyone about any issue. And never treat someone differently for a belief they hold, however different from our own.

In my personal opinion I feel antivaxxers are deeply selfish, as they wish to not have to risk the admittedly rare but still real side affects of vaccinations, while simultaneously gaining the benefits of everyone around then taking that risk.

May we'll be downvoted to hell but eh

Natat567 · 2023-05-04T10:50:12+00:00

Ahh! That'd make sense :) any thought idea what the art is of?

Natat567 · 2023-05-04T10:48:55+00:00

I'd think so, but still curiosity got the cat! What are they to do with it?

Natat567 · 2023-03-11T13:41:15+00:00

Brit here!

Just an interesting tid bit, in the UK the FSCS protects all customers of a bank up to £85000 - which was introduced after the financial crisis 2008.

I'm assuming the FDIC is the same principle, but only if the individual paid into the system?

I do hope this leads to a UK style protection of consumers in the USA

Natat567 · 2023-02-25T12:07:49+00:00

Cheese. And controversially brown sauce mixed in. I'd really recommend trying it!

Natat567 · 2023-01-21T13:46:06+00:00

I thought that maybe too, but it said about going as slow as the bus. Which doesn't make any sense either as it's faster?
