why do people sweat more in chennai???

One of the famous ornament of chennai is its summer!. Everyone here would have at least once talked about its effect and the way they affected. People comes out with sweats flowing from the body is the usual scene of chennai noon. The sweat produced is not just due to the temperature of the region. It is in fact due to the high humidity of chennai.

To explain this lets see a fact, people in chennai sweats more than the people in delhi where the temperature is higher than the former.

This is because of chennai's location. Chennai is located near sea due to which sea water evaporation is high during summer which in turn increases the humidity (Amount of water vapour present in air).
Normally human blood temperature is about 35 deg Celsius. If the outside temperature is more than that, then our system tries to automatically cools down by releasing sweat from the body.

The sweat which is released cools the surrounding heat by converting into vapour thereby reducing the body temperature. Here the Humidity comes into effect. Cities like chennai has humidity of around 95% resists the sweat to be converted into vapour. So the body temperature doesn't cools down and increases more amount of sweat from body.
The increase in body temperature causes reduction in blood flow to the brain which makes us feel tired. To overcome this we drink lot of water and juices during summer to make us cool.

Sweating is not seen in reptiles like snake because it changes its blood temperature with the surrounding temperature. So it can roam around at hot sun without getting tired. Better than us isn't it?.

Puththu kovilum Putho tilesum, as they are built

Its the grand Aadi season here in Tamil Nadu wherever you go you'd be followed by awful noise from no mercy speakers masqueraded as a devotional song. Yes, this is the first post dedicated to it. Hindu is not a religion but it's idealism, a way to unite people, that's perfectly constructed by assuming separate task to every God, no single God worship. Hindus moved from nature worship to idol worship, but that doesn't mean that we don't have nature worship we have created an idol for them and continued to worship them in a different form. Snake is a beautiful reptile, I have made friend with few too... Our ancestor found the natural law, 'every living creature on earth is important for the ecosystem to be balanced'. Maybe to make sure snakes are not killed fearing their venom they made them as God too! Not just idol snakes, they are worshipped as they are at their  conquered (from rats and termite)   nest or  puthu . Puthu...

Even bull shit can take you to top

Once there was a bird who was so complaining about its illness which is not letting it fly to the lowest branch of tree. The bull which was hearing this smacked some flies on its dick and started "well then have my shit you'd get better". On hearing this the bird sitting on the back of bull got shocked but hesitantly it was ready to give it a try. The day after bird overcame its thoughts and started pecking on the dunk, first day itself bird was able to fly to the lowest branch of tree. Excited the bird took more shit and the following day, its was becoming healthy and fat. Within a week it got so well that with few strokes its able to reach the top of tree.  The farmer some feet away spotted the bird, went into home came out with air gun and shoot the bird down. Moral of the story: Even bull shit can take you to top, but it won't help you to stay there This story is pretty old but always good for a smile :) heard it in a 'inner management' video of Sadh...

Wings of Fire

Though tagged under review I’m going to try and bring the essence of the book, in no means I have the guts to write a review on a book that’s written on/by Dr APJ Adbul Kalam. Unlike regular biographies the book is filled with information and facts on Indian Space research straight from Dr Kalam’s diary, has very limited information on his personal life. From Preface of the book, we can understand Mr Arun Tiwari co-author of this book had brought up this idea to write a book and put it work. The book is organized in seven sections but the core content is put inside 4 sections – Orientation, Creation, Propitiation, and Contemplation. While the rest cover how and why this book formed and what it intends to convey. Dr Kalam being a spiritual person has quoted poems and lines from the Quran throughout the book. Orientation starts with the birth of the legend Avul Pakir Jainulabdeen Abdul Kalam in Rameswaram to Ashiaamma and Jainulabdeen, Dr.Kalam’s father is a humble boat owner a...
