I don't know about you, but at this present phase of my life, I feel as though my time is running out. Every day as the clock ticks, I hear minutes of my life drifting away. If this is how I feel at 23, how will I feel in 20 years time?
According to statistics compiled by the World Health Organization, I only have another 60 years ahead of me if I am to live the life of an average female in the UK.
Of course, this is nothing to sniff at. If anything, I should be celebrating my luck given that if I'd been born male or in a different country, my life expectancy would be significantly lower.
And, for another example, a woman born on exactly the same day as myself but in India is statistically expected to live 14 years less.
Meanwhile, men in Russia on average live for 64 years, whilst their female equivalents are blessed with 76 - an additional 12 years, for those who are struggling with the math.
In fact, given that the average life expectancy of someone from Sierra Leone is 50 years, I should think myself lucky.
And, trust me, I do. I am very aware of my privileged situation, but I am also very aware that technology is forever adapting and that as a result, there may be a possibility for humans to live longer lives than ever before.
Until now, the idea of an infinite life, or a longer than average life was reserved solely for superheroes, Gods, and supernatural creatures, such as Dumbledore, Edward Cullen, Thor and Yoda. But, according to some prominent scientists, we could be soon set to outlive them all - even Thor, who boast an age of 1,000 years.
Of course, we are all aware of the perils of seeking eternal youth, given that those who have attempted to lengthen their lives - such as Walter Donovan in Indiana Jones and the Last Crusade and Dorian Gray in Oscar Wilde's classic novel, A Picture of Dorian Gray - have all come to a rather sticky end.
But the negative perception surrounding youth seekers could soon be over, given that humans could soon be living for several centuries rather than several decades.
According to Cambridge-educated English biomedical gerontologist and mathematician (in simple form: a man who knows a lot about numbers and the aging process), Aubrey De Grey, someone living on this planet today could have the ability to live until they're 1,000-years-old.
According to De Grey, an extremely well-respected expert in the field, the first person to live to 1,000-years-old has most likely already been born. He estimates that that person is currently aged between 50 and 60 years old.
He argues that most of the fundamental knowledge needed to develop effective anti-aging medicine is already in existence, but that funding is holding science back from fully exploring the possibilities.
Luckily, De Grey's research has received a great deal of financial support from numerous Silicon Valley CEOs, including the PayPal billionaire, Peter Thiel who donated $2.4 million to the cause.
"Ageing is a disease that can and should be cured," says De Grey, matter-of-factly. "I've been ridiculed but finally people are starting to come round to my way of thinking. Anyone who has ever wanted to change the world has been attacked."
His "way of thinking" is that, if treated like a vintage car, the human body can survive for centuries. "Replace the parts, clean it up, keep it running smoothly way past its expected expiration date," he explains.
Of course, this doesn't account for those who die of unnatural causes, such as suicide, murder or traumatic accidents.
"There is no reason that someone living today shouldn't live to 500, 1,000 years," says De Grey. "As the technologies improve, lifespans will increase."
To prove his theories, De Grey has cited research which he claims prove it is possible to extend the lives of mice, fruit flies and worms - creatures infinitely different to humans, however.
Meanwhile, Nir Barsilai, the director of the Institute for Aging Research at Albert Einstein College of Medicine is not entirely convinced by De Grey's claims. "Based on the biology that we know today, somewhere between 100 and 120 there is a roof in play and I challenge if we can get beyond it," he says.
The oldest person to ever live is a French woman named Jeanne Calment, who died in August 1997 at the impressive age of 122 years and 164 days old.
But, De Grey doesn't let these criticisms perturb him from his quest to find the cure for aging. "150,000 people die every day worldwide and of those people, two-thirds die of aging one way or another," he says. "If I bring forward the cure for aging by one day, I've saved 100,000 lives."
Of course, if De Grey is successful in his attempts to avoid death then the world is set to face some rather challenging times.
Without death, overpopulation is inevitable. This additional strain on resources will almost certainly cause a great deal of calamities - and, ironically, probably lead to many premature deaths due to hospitals being unable to cope with the demand.
Knowing this, I will be honest and say that the 60 years of life which I am statistically owed look quite blissful. Surely there is nothing worse than living for 1,000 years? That is, unless you're a rich Silicon Valley CEO who won't be able to spend all their money in the average allotted time - no wonder they're funding the research!
