2025.05.02 – Microorganisms, Workmanship, Memory and Vitamin B12: Clear Facts for Everyone – My Diary

Bacteria start working on a body very soon after death.
🦠 They live inside the body even before death.
Clostridium and Pseudomonas are common decomposers.
💨 They produce gases and make bodies swell.
Fungi such as Aspergillus appear later in the process.
🍄 They help break down what’s left.
Archaea create methane gas in places with no oxygen.
🔥 That gas can make pressure build up.
Actinobacteria take care of tough tissues like cartilage.
🧫 They finish what bacteria and fungi start.

Some microbes eat metals and cause corrosion.
⚙️ This is called Microbially Influenced Corrosion (MIC).
Thiobacillus ferrooxidans oxidizes iron and sulfur.
🔬 It creates acid as a byproduct.
Desulfovibrio bacteria reduce sulfate and make hydrogen sulfide.
💥 That gas smells like rotten eggs.
Gallionella ferruginea uses iron and forms rust.
🛠️ It often grows in wet pipes.
Leptospirillum species dissolve metal ores in acidic environments.
⛏️ They are common in mining systems.

Workmanship Standards are clear quality rules for physical work.
📏 They define what a good product looks like.
IPC-A-610 (Acceptability of Electronic Assemblies) focuses on electronics.
💻 It explains acceptable soldering and alignment.
ISO 9001 (International Organization for Standardization 9001) applies to many industries.
📦 It sets rules for managing quality systems.
MIL-STD-2000 (Military Standard 2000) guides military soldering practices.
🔩 It expects precision and cleanliness.
Standards help reduce errors and improve inspections.
🧰 They also guide training for workers.

Memory is how the brain stores and uses information.
🧠 Problems can happen at any age.
Amnesia means someone forgets big parts of their life.
🛑 It can come after a head injury or trauma.
Dementia includes many brain conditions.
⏳ Alzheimer’s disease is the most common type.
Mild Cognitive Impairment (MCI) is a small memory issue.
🔍 It might get worse over time.
Depression or anxiety can make it harder to think clearly.
🌧️ Feelings affect memory.
Poor sleep and stress damage memory, too.
🛌 The brain needs rest to remember.
Alcohol and drug use can erase memories forever.
🍷 Some brain cells may never recover.
Low vitamin B12 makes people forget more often.
🥬 It also causes confusion and tiredness.

Vitamin B12 (also called cobalamin) is important for the brain and blood.
🧪 But the body only uses what it needs.
Most extra B12 leaves through urine.
🚽 That’s why overdose is rare.
Very high doses may cause acne or skin rashes.
🩹 Some people get red bumps or irritation.
Some feel nausea or have diarrhea after too much.
🤢 The stomach may not like the excess.
B12 might make blood pressure go up in sensitive people.
💓 Palpitations or fast heartbeat can happen.
In rare cases, people have allergic reactions to it.
🧯 That includes swelling or trouble breathing.
Lab tests might show strange results with too much B12.
🔎 It can hide other health problems.
