It seem a bit difficult to get the right topic for this post, but what I tittle it is not bad anyways.
Have you ever wondered why culture places ban (so to say) on some natural phenomenon that takes place in our body system?

Now your question is how?

Alright, grab a sack of popcorn, sitback and let me drive you through the lane of this whole gist.
I was born and raised in a society where it is considered an offence for the younger one to 'gas out' in the presence of an elder. yeah...!, that's true. Infact, this belief is prevalent in our cultures today. And though it seems awkward farting in the midst of people, you shouldn't try to stop the gas for too long.

'flatulence', 'passing gas', 'passing wing' or 'farting' are the common names. It is cause generally by the release of gas during digestion process or respiration in our internal system. The stinky, pungent and rotten smell can be as a result of sulphurous gasses like hydrogen sulphide.

Let's now talk about the topic 'why you shouldn't stop the fart'.
First, it is a cure to some diseases. when you fart, the faul-smell and pungent odour that causes the person next to you to squeeze his face and tighten his nose is beneficial to the body system.

Fact:

Flatulence contain hydrogen sulphide. According to a research carried out by some scientist from the University of Exeter , this gas prevent mitochondrial damage which could lead to the prevention of heart diseases,anthritis,stroke. etc.
Secondly , it gives great relief
Let's tell ourselves the truth, how do you feel after releasing a long-held gas?
Refresh, loosen-up and free Right?
Yeah! That's what I'm talking about. Holding in gas make you moody and uncomfortable.

conclusion

Fart just like any other body waste is not meant to be in human for too long, so when you have the urge, let it go but don't be the reason why a gathering will dismiss before time with your stinky odious...... Gas..
Thanks for the time.
