Queen may have melancholically wondered who wants to live forever, but were pretty sure theres a few people out there that actually do. There are a few remarkable lifeforms out there that appear to be able to regenerate their cells Doctor Who -style, entailing they can technically live forever but this is something thats currently beyond the capabilities of humankind.
Does a new analyse give the dream of afterlife a credible boost, though? Writing in the journal Preventative Medicine, a squad from Brigham Young University has discovered a strange route to slow aging, but one that comes with a genuinely frustrating catch.
Age may be defined colloquially as how many times each of us has orbited the Sun fair enough but our cells dont inevitably all age in the same route. If we have an unhealthy lifestyle, our cells worsen quicker than if we have a more pious style of living. Its far less fun that way, but sadly its true.
It shouldnt come as a surprise, then, that this new survey has concluded that workout, of all things, allows our cells to age far slower than they otherwise would. Specifically, adults with high-intensity exercising levels, such as 30 -4 0 minutes jogging for fives days per week, appears to keep your cells nine years younger than your birthday cake would suggest.
Its all linked to your cells telomeres, the protein hats that sit at each end of our chromosomes. Every day a cell replicates, the hats become shorter. The more they shrink, the more we age.
To wit, this study took a look at the data of 5,823 adults that took part in the Centers for Disease Control and Preventions( CDC) National Health and Nutrition Examination Survey. Apart from a whole host of other things, the telomere lengths of the participants were also recorded.
The team found that those with the shortest telomeres and thus the greatest signs of cellular aging received from those who lived a sedentary lifestyle. Those with intense activity had the longest and youngest telomeres.
Frustratingly, only quite severe levels of physical activity appears to make a difference in this respect. If you think you can age nine years slower by having a quick walking to the shops or even a brief go on the motorcycle, forget it the team found no significant differences in telomere length between those with low-to-moderate-intensity exercising levels and couch potatoes.
Although the youthful mechanism of telomere preservation is unknown, its likely because exercise suppress inflammation and harmful chemical imbalances, both of which are able to injury those little chromosome hats.
So there you have it if you want to stave off demise for a bit longer, youre going to have to sweat for it.
