Causes of Premature Ej*******on.

PE is a condition where a guy ends up finishing much sooner than he or his partner would’ve preferred.
This affects the s*xual health of couples and must be avoided at all cost.
This can be quite a discouraging experience and there are several different things that may cause a premature ej*******on. Let’s take a look at five of those causes now.

1. Substance abuse
2. Anxiety and depression
3. Hormonal imbalance
4. Inexperience
5. Over excitement

The Chemical Basis of Inheritance.

The nucleus of a cell is an organelle that carries all life activities. Inside it is the thread-like material called chromosomes that bears the information molecules DNA and protein. DNA is a nucleic acid composed of repeating units of deoxribose sugar, a phosphate and nitrogenous bases viz Adenine, Thymine, Guanine and Cytosine in a double stranded form.
🧬 DNA contains the information a cell requires to make proteins which is the building blocks of the body.
These nitrogenous chemical bases make up combinations with permutations and combinations to make up double helical structure of DNA where Adenine binds with Thymine and Guanine binds with Cytosine. Just like the words on a page when stringed together act as a blueprint that tells the cells of the body when and how to grow, mature and perform various functions.

Note : there are two types of nitrogenous bases namely, purines (adenine and guanine) and pyrimidines (thymine and cytosine).

Breaking The Chain of COVID-19!!

The chain of infection is the condition or link via which an infectious disease spreads in a population from person to person.

There are 6 links or chain of infection. Namely:
1) the causative agent
2) the reservoir
3) the portal of exit
4) the mode of transmission
5) the portal of entry
6) the susceptible host

All these links must be intact for an infection e.g covid-19 to be established.

One of the ways to prevent the spread of infections e.g. covid-19 is to identify the weakest link in the infection chain. I make bold to tell you the weakest link is the mode of transmission.

Mode of transmission: this is the method through which the pathogen gets from an infected person to the new host.
This may occur through direct contact or indirect contact, vector transmission, food ingestion or airborne.
But in the case of covid-19, it's via contact with an infected persons respiratory droplets which can be inhaled or can contaminate objects like door k***s, hands and other objects one can easily touch. This droplet carrying the virus enters a susceptible host via orifices viz nose or mouth.

So how do we break the chain?
We break the COVID-19 chain by adhering to the following:
*maintain at least one & half & at most 3 meters distance away from anyone that is sneezing and coughing; Social distancing.
*wash your hands, before, during and after food preparation with soap.
*always use hand sanitizer and remember to wash of the germs rather than recycling them.
*cover your mouth and nose with flexed elbow or tissue when coughing;
*avoid hand shaking
*maintain a high level of personal hygiene.
*eat healthy
*don't go out when sick of any kind.
*stay informed properly and follow instructions.

Help break COVID-19 chain of infection!!
