What would first come to our mind would be the fundamentals that ensure our survival – Air, Food and Water. These are the basic needs to sustain human life that we learn about in science.
Our bodies need a consistent supply of oxygen to our brain. Otherwise, we would experience hypoxia (lack of oxygen) and brain damage.
Without food, we won’t have the energy we need to work. When the body has no more internal energy sources to draw from, it’ll break down your muscles into proteins for energy, leaving your body very susceptible to infectious diseases which can end up killing you.
We are made up of 70% water and must aim to keep ourselves hydrated before the dehydration process sets in! Loss in water volume will lead to a reduction in blood, which reduces the flow of blood to the brain, making it impossible for us to focus.
You can (at most) survive 3 minutes without air, 3 hours without shelter, 3 days without water, and 3 weeks without food!
But is that all?
Blood is a life and death issue
(Don’t worry, that’s just ketchup!! :p)
Every second of every day, blood is the medium which delivers vital nutrients and transports oxygen and other chemicals to all your organs, while also bringing away body’s waste. The blood flowing in you also warms you up and creates antibodies to protect you from germs.
However, the very liquid that keeps you alive can also kill you. Within hours, or even minutes, blood can spread poisons over your body. If your bloodstream does not have the right defenders to fight against the deadly diseases, your life would be at risk.
Every single night, it’s as if your parents have nothing more to say to you other than “sleep early!!”. As much as we may hate to sleep early (because staying up is a pretty cool thing), we actually need the 8 hours of sleep that we should be getting.
What will happen if you don’t get enough sleep: headaches, hallucinations, memory impairment, difficulties concentrating, lack of clear thinking, and many other health problems in the long term.This list… sure sounds scary! And I don’t wish to scare you…but that is the sad, sad reality. (I’m sure you know what to do now)
Apart from these psychological needs that all living things need to survive, what distinguishes us human beings from other living things is that we have many other motivations to live! What do you live for?
Life itself is an invitation to learn, no matter how uncompromising the situation can be, in times of good or bad. We seek to make the best out of each and every single day for as long as we live, to do the things we like, to achieve the goals we have and primarily to live for the people we love.
Just like the waves of ocean, life is not static, but in constant movement. With each waves comes new experiences, and each one is different. A wave rises for a brief moment and falls back down the next, a reminder to us that life is a roller coaster, with good and bad times, and that nothing lasts forever.
As long as we have the will to live, we will be want to stay alive. For our family, our friends and our aspirations. For if we don’t live to see the next day, we wouldn’t know what we are missing out on.
