Not only has he defied all odds by beating the ongoing medical pandemic, but he has also lived through the worst pandemic in modern history. Just to refresh your memories...

Back in 1918, decades before the current medical crisis, the world was brought to its knees.

101 years prior to this pandemic, the notorious Spanish flu ripped across the world, infecting and killing millions of people.

It became the most severe pandemic in modern history.

The origins of this deadly strain of influenza are still uncertain but, much like the current virus, it was notoriously quick to spread across the globe.

An estimated 500 million fell ill to the virus.

And roughly one-fifth of those died, with some indigenous communities even being pushed to the brink of full extinction.

It was a dark, dark time for the world.

And, here in the United States, we were hit particularly hard, with around 675,000 deaths been recorded in our country alone.

Age played a huge role in survival chances.

The 1918 pandemic was unusual in that it killed many healthy twenty to forty-year-olds, including millions of World War I soldiers. In contrast, people who die of the flu are usually under 5 years old or over seventy-five.

Both medical research and resources were limited back in 1918...

So the virus was quick to rampage out of control, with prevention efforts being limited to non-pharmaceutical interventions such as quarantine, good personal hygiene, and limitations of public gatherings... It all sounds a bit familiar, doesn't it?

And now, fast forward to 2020, a new pandemic has brought the world to a standstill.

Since December 2019, the deadly virus has been spreading across the world like wildfire and it doesn't seem to be slowing down.

Much like the Spanish flu, this pandemic has caused a global panic.

According to statistics, over 3 million people have now been infected with the virus, and a further 230,390 have died.

The majority of people around the world have been left confined to their homes...

And, unlike the 1918 pandemic, it is this time the elderly who are most vulnerable to the virus.

Older people are in one of the higher-risk demographics...

And the majority of deaths so far have been people over the age of sixty.

But, with the many devastating deaths this pandemic has caused...

There are stories of hope.

And Rudi Heider's is one of those.

Rudi is a great-great-grandfather who has lived through the Spanish Flu, Great Depression, and World War II.

Sadly, Rudi tested positive for the deadly virus.

And battled the virus for weeks while quarantined at a nursing home in Chesterfield, Missouri.

Rudi's grandson, Matthew Heider and his wife, Janet, had recently welcomed a grandchild of their own...

And had spent the last month praying that Rudi would make a recovery, despite knowing the odds were not in their favor. "He was fighting fevers, I think he was at 102° and he had said he wanted to die...I cried,' Mathew's wife, Janet, told 11 Alive.

But, unbelievably...

On Tuesday, his family received some incredible news.

Rudi had beaten the virus...

But the day was even more special for the family.

Why?

Because it was Rudi's 107th birthday!

When asked what his grandfather's "secret" was...

Matthew said: "I think a lot of it is definitely having a positive attitude and his mind is so active."

At 107, Rudi is believed to be one of the oldest people on earth to recover from the virus.
