When they meet

One fine morning, when Ajay and Nina were on their morning walk they met their freinds Archana and Rajiv . "What a pleasent surprise!!! It is been a long time after 20 years. "said Nina."Hi there." said Ajay. From the right were coming, Rashmi and Aarav. Surprisingly they both were

wearing trekking clothes. Ajay asked Aarav why they were wearing trekking clothes? He answered ,"Because we just climbed the mountain Bhima Shankar that is in Lonavala.""Wow that might be a great expirience!"said Nina. That day after they're morning walk they planed to meet in the jogers

park. When they all reahced there they planed to go for a trek to Duke's nose in Lonavala they decided to leave on the 28th of August that was Archana's birthday!!!

The trekking trip begins

On the day of the trek Archana was wearing a nice suit for trekking, as it was her birthday.

3 hours later..........

Archana's legs hurted terribly, where as Nina felt dizzy in tthe heat. Rajiv's back felt that it broke ,

Rashmi felt sick and everybody fainted. Some time later everybody woke up in a unknown place but it felt like they all had reached the mid mountain.

30 mins later.....

everybody walked more and more and more and more and tried their best to not fall. They stoped for lunch and ate hot noodles. When they finished thier lunch they again walked more and more and more and more and walked more

and more and more and more and walked more...

The big explosion

While everybody walked there was a big exlosion . When they woke up they realised that their body structure and age was like how they were in college and were there in their college. But yes somehow they all got to know how

they reached in this time......At night Archana had a wierd dream.. In that dream she was on the same Duke's nose trek but none of this had taken place she saw that all of them dissapiared into a wind and went somewhere but she could not know where.

After some time Archana woke up and realised that it was a dream. The next day when they went in their classes only the topic Changes that the body goes through as we grow old were going to be taken they were surprised because they were never taught this topic in

college. As they all were in different classes they had different periods. Archana's first class was Medicine in which they learnt that there are 10 main systems in ones body those are the circulatory, respiratory, digestive, nervous and endocrine systems. They

 also include the immune, integumentary, skeletal, muscle and reproductive systems. But they mainly focused on the Nervous and Urinary system.

Chapter 4....

The learning express

"The Nervous System..."said the professer "The nervous system includes the nervous. The nervous system is the parts of the body that gives signal all over the body. As we grow old this system becomes weaker than usual and we get numb.The nervous system is network of nerve cells and fibres

which transmits nerve impulses between parts of the body."

Urinary system...

"The kidneys tend to become smaller because the number of cells decreases. Less blood flows through the kidneys, and at about age 30, they begin to filter blood less well. As years pass,

they may remove waste products from the blood less well. They may excrete too much water and too little salt, making dehydration more likely. Nonetheless, they almost always function well enough to meet the body’s needs."

Rajiv's 1st class was Biology in that they only studied about sensory system.

"Sensory system includes of skin, ears, tounge, nose and eyes, but as we grow old most of the people dont have a verygood vision or they cant listen properly. They might as well not be

able to taste salt or sugar and tell difference in between them they even go numb because their nervous system dosent work prperly like ours."As Nina and Rashmi were in the same class their first subject was Science. They focused on the Muscular, Immune and Digestive systems.
