so I’m going to talk about the thymus gland and why it shrinks down to nothing

as you get older it’s a very very important gland as it relates to your

immune system because it is the training center for your immune cells

specifically the t-cells which stand for thymus cells and this gland is right

underneath your breastbone right on top of the heart not to be confused with

your thyroid which is a little bit higher up right here the thyroid and the

thymus are completely two different separate glands now when your infant you

have this huge thymus gland and the reason why it’s huge is because it

doesn’t have all the experience yet it has to go through practice by being

exposed to germs and develop or acquire it’s immunity because the t-cells are

part of the immune system that relates to adaptive or acquired immunity so you

have to be exposed learn from this experience and develop immunity over

time and as you age it starts to decrease in size by the time you’re like

75 years old it’s virtually replaced by fat and they call this thymic involution

okay or or thymic atrophy atrophy means it shrinks okay so without that gland

working or even being there your risk for infection goes up your risk for

getting cancer goes up your risk of getting an autoimmune disease also goes

up because one of the key functions of the thymus is to prevent or protect

against autoimmune diseases and one of the theories that contributes to this is

a decreased amount of antioxidants and then you’re gonna have all this

oxidation which is gonna kill more cells so if that is true which it might be it

validates the idea of consuming a good amount of vegetables leafy greens

preferably raw throughout your life but the thymus is involved with these

t-cells so we have the T killer cells these are antiviral they’re also anti

tumor they kill tumor cells and then we have the T helper cell

this cell is like the commander of the entire immune system so the HIV virus

for example targets this cell and it takes out the entire immune system so

the T helper cell is not necessarily the quarterback of a football team it’s the

coach of the football team in which they are helping design the plays

coordinating what everyone does to help win the game so you take this guy out

and the whole thing kind of goes downhill so that’s what the T helper

cell does now the T regulatory cell or t suppressor cell is involved with

suppressing an overactive immune system so it’ll put out inflammation it also

specifically helps prevent autoimmune diseases so you take this thing out and

then your risk factor goes up now when you hit age 65 the diversity of these

cells diminishes significantly so basically this all increases your

susceptibility to having problems now what’s interesting about this Koba 19 is

that it seems to be when you’re below 65 and healthy the risk factor from dying

from this virus go down so significantly that the odds of you dying are very

similar to the odds of you dying in a car when you’re traveling to work yet

when you go over 65 it kind of goes up so apparently 65 is kind of a key age

for your immune system so now the question is what can we do we can’t

control aging we can control our health and other things number one we can start

to beef up no pun intended our antioxidants from vegetables that

could help us number two keeping the stress lowered stress by itself I’m

talking about sustained stress like cortisol has the ability to shrink the

thymus gland as well as your lymphatic glands like the lymph nodes so excessive

stress can cause atrophy of your immune system next thing is very very

important and I’m gonna put some research down below if you have a zinc

deficiency one of the symptoms is this your thymus gland actually atrophies so

how difficult would it be just to take some zinc on a regular basis very very

important for your immune system to maximize and optimize the size of your

thymus glands so you can keep this going as much as possible now through your

life if you’ve been exposed to germs you have a tremendous amount of antibodies

sitting there to help protect you so it’s not that you need to keep the

training going for these t-cells like you were when you’re a kid but it’s

important to maintain this thymus gland so you can keep your resistance to

infection very very high one more thing I want to mention if you are over 65 or

even over 75 there’s a really good support remedy that you could get

thymus extract now I’m not going to recommend any brands you’re gonna have

to do the research by yourself it’s a glandular extract that you can

get freeze-dried and take a little bit each day that can greatly help support

your immune system specifically the thymus gland take a very small amount

initially and gradually work up to maybe even like one capsule per day don’t

take the whole capsule right off because it could wake up the immune system and

create a little bit of a reaction but if you take just maybe a half a capsule

with food and take it for like a couple weeks and then slowly increase it a

little bit more and more I think that can support your immune system alright
