The Reason Why We Can't Live Forever

Every day, every single person is growing older and older. It might be depressing to think about, but eventually, we will all die. But how long could humans live for? Trace takes a look at how examining the blood of the world's oldest person could tell us how long humans can survive.

We All Have Cancer, But How Much?

Dr. Ed Park discusses cancer and how it is potentially related to the erosion of telomeres. It's likely something we all have, possibly at many times throughout our life. But certainly not all of it is life threatening. What is the difference and how many times do we actually get cancer? That's what is discussed in this video.



It is with a sad and heavy heart that I say this, my recent surgery showed each site was cancerous with no margins. Stains showed mass deposits all over my left side and back, with deep deposits towards internal organs.

Time frame is irrelevant now, I do not want to tell anyone what is expected to happen now, until I am ready.

I should explain for people I was told to enjoy the next two weeks as after that they expect me to be to sick to enjoy life.

I am still going to have my samples tested in the hope we can save a life in the future, I will do everything in my power to make that a reality! We will all continue the research!

My family and I knew this day would come, but it has come faster than any one expected, my team are fighting for me to try everything possible, but my body is failing fast, I can feel it and we all know it.

No one should have to go through this mental and physical pain in this day and age. I will now be documenting the end of my life, my fight, my struggle in the hope that I can make people smile, laugh and spread some joy around the world.

In the less than 0.01% chance I manage to beat this, I will spend the rest of my life helping others in horrific situations, cancer is just one awful thing that affects people!

I will leave you with this, smile, laugh and see the beauty in everything everyday, make the most of being able to be you, but most of all never regret anything! Make every day count, because like me you may wake up unable to continue to do what you love.

My dreams are just that now, dreams, white clouds in the sky that I will never reach.

Much love and I'm sorry it's not better news.


Don't Give In! Don't Give Up!

Due to loads of interest you can now pre-order the #dontgiveindontgiveup hoodie and t-shirt now:

I have a Go Fund Me setup if you would like to support me get research done into this type of cancer (Pleomorphic Sarcomatoid Carcinoma and Primary Cutaneous CarcinoSarcoma) with the hope that we can eventually find the best treatment, as there are very limited / no options left now, I have already started passing on samples, medical files and reports to specialists worldwide. The next step is to get my DNA Sequenced, so as specialist medical researchers can see if we can find the needle in the haystack to treat this.

Not everyone can get the same type of treatment, not everyone is able to have chemo, radiotherapy, immunotherapy and the likes. I am one of those with a rare form of cancer that can't be treated by conventional means.

There is litterally no research into this type so it's important to me, to document everything and record it all, so that if something can be done and someone spots it, we have that added bonus!

We all die, so why don’t we die well?

Modern medicine has a fundamental failure in its approach toward aging and dying, says Dr. Atul Gawande: “We don't recognize that people have priorities besides just living longer.” Gawande, a surgeon and the author of a new book, Being Mortal: Medicine and What Matters in the End,” joins Jeffrey Brown to discuss his education in mortality.

Why Haven't We Cured Cancer Yet?

Cancer affects millions of lives each year. With technology expanding at such a rapid rate, and survival rates increasing, why haven't we found a cure for cancer yet? Treatments like chemotherapy may help, but are there any promising, more advanced treatments to look forward to? Let's explore what cancer is, and understand why it's so dangerous.

Two-Thirds of All Cancers Are Caused by One Thing: Your DNA

While environmental factors can play a huge role, the number one cause of cancer is mutations from regular cell replication. Does this mean cancer in humans is simply inevitable?

Researchers Find Mutation 'Hotspots' That Are Linked to Cancer

Researchers say they've identified clusters of genetic mutations in proteins that can give rise to cancer, a discovery that may help them zero in on new treatments. Those mutation 'hotspots' occur among families of proteins produced by genes in the body's cells. By sifting through data from nearly 6,000 cancer patients, researchers at the University of Maryland say they found thousands of mutations that occur among those proteins.

Bad luck plays larger role than environmental, genetic factors in determining who gets cancer

Two-thirds of adult cancer incidence across tissues can be explained not by environmental factors or inherited genes but by bad luck, according to scientists from the Johns Hopkins Kimmel Cancer Center. The unlucky findings by Johns Hopkins scientists were discovered using a statistical model that measures the proportion of cancer incidence across many tissue types. They found that more often than not, cancer in adults is caused by random mutations that occur when stem cells divide.

DNA typos to blame for most cancer mutations

Each time a cell divides, it provides an opportunity for errors to crop up during DNA replication. In 2015, Vogelstein and one of his co-authors, mathematician Cristian Tomasetti of Johns Hopkins University in Baltimore, created a stir with an analysis that looked at possible explanations for why some cancers occur more often than others. They concluded that differences in the number of stem-cell divisions in an organ correlated with the frequency of cancers in that area.
