Q: Is a ageing among the greatest known risk factors for most human diseases: of the roughly 150,000 people who die each day across the globe? ¶
A: Yes, and about two thirds die from age-related causes.
Q: Is an ageing the nematode C? ¶
A: Yes, elegans, thanks to its short lifespan of 2–3 weeks, our ability to easily perform genetic manipulations or to suppress gene activity with RNA interference, or other factors.
Q: Is an ageing regulated specifically by reproductive hormones that act in an antagonistic pleiotropic manner via cell cycle signalling? ¶
A: Yes, and promoting growth and development early in life to achieve reproduction, but becoming dysregulated later in life, driving senescence in a futile attempt to maintain reproductive ability.
Q: Is an ageing uncertain? ¶
A: Yes, current theories are assigned to the damage concept, whereby the accumulation of damage may cause biological systems to fail, or to the programmed ageing concept, whereby internal processes may cause ageing.
Q: Is an ageing the result of chance damage that accumulates over time? ¶
Q: Is a ageing a "global phenomenon," that is occurring fastest in developing countries? ¶
A: Yes, and including those with large youth populations, and poses social and economic challenges to the work which can be overcome with "the right set of policies to equip individuals, families and societies to address these challenges and to reap its benefits".
Q: Is a ageing among the greatest known risk factors for most human diseases? ¶
Q: Is an ageing the increase in the number and proportion of older people in society? ¶
Q: Is an ageing seen in five different views: ageing as maturity? ¶
A: Yes, and ageing as decline, ageing as a life-cycle event, ageing as generation, and ageing as survival.
