The fact that more people have the opportunity to live to a healthy old age and contribute to the economy.
A european union roadmap to promote healthy aging using a holistic approach for a sustainable global future.
A Horizon 2020 project with wearable tech diapers, It aims to use an algorithm to analyze the microbiome of the frail elderly.
A tourist resort on Bahamas aimed at only people aged 80+, encourages surfing as a way to stay healthy and active.

0,3 %
1,0 %
1,8 %
2,7 %
4,7%

--------------------
Okinawa is a "blue zone" where people have unusually healthy lifestyles and longevity, approximately how much longer do those people live than the average western european?
12 years

What's the approximate ratio between the number of people dying yearly of Alzheimer's disease VS malaria in Africa?
50:50
10/90
80/20
30/70
40/60

--------------------
Which of the following statements are true?
Life expectancy is predicted to reach 104 in Europe by 2050, epigenetic expression due to better environmental conditions is likely to make some currently living people reach the ages 135-140.
In Sardinia there is a small village called Piazziano where people live on average to the age of 108.2, this may be the result of local wine and maggot cheese and laughing on average 2.5 h a day. However studies done by researchers at the University of Milan suggests that the longevity might be caused by psychology, since the local church believes that everyone who dies always will burn in hell forever it means that elderly people are encouraged to carry on living.
The most common age of death is not increasing, supercentenarians are not living longer, exceptional longevity has not been identified to be linked to special genes or lifestyles and even genetically identical animals kept under the same conditions differ in lifespan due to randomness.
There is solid data that french women live on average 1 year longer than swedish solely due to the extra resveratrol from their higher red wine consumption.
Married women with many children tend to live longer, probably because they often have more estrogen and serotonin

--------------------
What is the chance of living to 65 in Sweden? (based on people born 65 years ago)
91%
86%
81%
70%
64%

--------------------
Which of the following alternatives describes most accurarely the current evidence of a maximum human lifespan?
Mortality rates stop after age 105, so people can live much longer after that, perhaps to age 160, the biological basis of this is clear as fruitfly experiment suggest.
Most of us can expect to reach our individual potential which is around 100 if we eat healthy and exercise, then we will die from healthy normal aging instead of from diseases.
The maximum lifespan is about 140 years old, however many factors strongly limit our natural lifespans. Examples include nuclear powerplants, plastic straws polluting our environment, pesticides used on vegetables and most importantly gluten.
The oldest people in the world tend to be 115-117 years old. From a physical perspective life can be extended indefinitely, but the repair system fails at roughly similar rates in the absence of intervention so that virtually noone can live much beyond 115.
No, we have to do more studies to know at what ages people die.

--------------------
Does the period of physical growth in an animal always correlate well with how long it is going to live?
Yes, this is explained by children hitting puberty earlier and subsequently age faster
No, Ostriches can live to age 80 despite being fully grown before the age of 2, while humans grow until 20 and still only live to 80, furthermore the greenland shark doesn't reach sexual maturity until around age 160 and is believed to be able to live 500+ years.
No, the neurons involved in circadian rhytm which controls growth is not influenced by the pituitary which controls the rate of aging
Yes, mice live very short because they reach puberty early
No, long life is encoded by different chromosomal regions that controls timing of puberty.

--------------------
10. Do we have evidence that metformin extends lifespan in a human population?
Yes, many centenarians have taken metformin for decades
No, since aging is not a disease we cannot give people metformin
Not proof, but it sharply reduces the risk of cancer and heart disease which should be expected to give a few extra years for many people
Yes, type 2 diabetics who take metformin but stay obese live on average to 71, the ones who stay obese but take rosiglitazone live on average to 68
No, metformin has been tested on too few people to draw any conclusions about how it affects human biology.
