Epigraph:
It is Allah Who created you in a state of weakness, and after weakness gave strength; then, after strength, caused weakness and old age. He creates what He pleases. He is the All-knowing, the All-Powerful. (Al Quran 30:55)
He it is Who created you from dust, then from a sperm-drop, then from a clot; then He brings you forth as a child; then He lets you grow that you may attain your full strength; then He lets you become old — though some among you are caused to die before — and He lets you live that you may reach a term appointed, and that you may learn wisdom. (Al Quran 40:68)

Human life spans may be limited to a maximum of about 115 years, claim US scientists.
Their conclusions, published in the journal Nature, were made by analysing decades of data on human longevity.
They said a rare few may live longer, but the odds were so poor you’d have to scour 10,000 planet Earths to find just one 125-year-old.
But while some scientists have praised the study, others have labelled it a dismal travesty.
Life expectancy has been increasing relentlessly since the nineteenth century – due to vaccines, safer childbirth and tackling killers like cancer and heart disease.
But can that go on forever?
The team in New York analysed data from the Human Mortality Database and the deaths of super-centenarians (those over 110) in France, Japan, UK and US.
The data showed increases in life expectancy were slowing in centenarians and that the maximum age of death had plateaued for at least two decades.
Prof Jan Vijg, one of the researchers from the Albert Einstein College of Medicine, told the BBC News website: “In people over 105 we make very little progress, that tells you we are most likely approaching the limit to human life.
“For the first time in history we’ve been able to see this, it looks like the maximum life span – this ceiling, this barrier – is about 115.
“It’s almost impossible you’ll get beyond it, you need 10,000 world’s like ours to end up with one individual in a given year who will live until 125 – so a very small chance.”
The oldest person

The French icon of longevity was born before the Eiffel Tower was constructed and met the painter Vincent van Gogh.
Nobody has since got near her venerable age.
Prof Dame Linda Partridge, the director of the UCL Institute of Healthy Ageing, said a limit to lifespans “logically has to exist”.
But she told the BBC: “Although this really interesting paper describes what is happening, it doesn’t describe what will happen.”
The crop of centenarians in the study were affected by malnutrition and infectious diseases in their childhood back in the late 19th Century. Remember smallpox wasdeclared eradicated only in 1980.
“It was certainly very different to what the current birth cohort will go through, but it could yet be rather negative as a lot of children have grown up obese and that could bring lifespan down quite a lot,” Prof Partridge added.
