what are the things(factors)that speed up oldness in human?

Hutchinson-Gilford disease (progeria) speeds it up most I know of. \n\nalso the other things mentioned:\nexcessive stress (physical or psychological),\nhealth risk factors (probably mainly being overweight, it's been shown skinny people live longer)

Age--having babies--weight loss or gain--I think many factors might contribute to that.

Apparently, sleeping less is one great way to increase your longevity... (see source)\n\nI don't agree with the comment regarding living in a 'First World Nation'. Currently, 1 out of every 6 children in the United States is obese. Maybe he meant "don't live in Texas".

this is an interesting question, because even if someone has a great diet and excercises and does not drink and smoke could die early and the opposite can live till 102...it really depends on the genes in this aspect and heredatary circumstances fall into place here too....but you can control it the best that you can..its hard to believe sometimes when you hear stories of people who chain smoke and drink all the time, never excercise and die in their 90's and on the contrary someone who does all the right things and dies of a massive stroke..just do the best you can and thinking positively and laugh alot, these are also factors to make you live longer..look at the all the comedians and conductors, they live a long time, i mean some of them dont look healthy, but they have what it takes..maybe its all psychological...

could just be age, genetics or vitamin deficency

Well, as one gets older, one's metabolism slows, and certain nutrients are not needed in the same quantities.

Old age is the major cause of disability in older people.

On the whole, doctors.  You have to understand that the personal and civic hygeine that plumbers make possible, indeed easy, was (at one time) prescribed by physicians...\n\nThe things that have done the most to increase human lifespan and reduce human disease and suffering are, metaphorically: soap, sewers and square meals.\n\nSoap:  This represents good personal hygeine; hand washing before eating or preparing food, after toileting, keeping the body as a whole comparatively clean, and particularly keeping wounds clean--that sort of thing.\n\nSewers:  Good civic hygeine.  This includes proper disposal of bodily wastes, but also garbage; it includes steps being taken to assure the purity and safety of the drinking water and the food supply; that sort of thing.\n\nSquare Meals: Adequate, but not excessive, nutrition.  This used to be making sure that you got not only your meat and potatoes, but your fruits and veggies, too.  It is a rapidly growing area, as we find that aviodance of some stuff (cholesterol, for instance, or sodium) or augmentation of the intake of others (lycopenes, calcium, magnesium, potassium, folate, and such) will improve long term health; and of course, it includes staying at or near the "ideal" body weight.\n\nIt's estimated that these three groupings of things--all of which, I might add, were once prescribed by physicians--are estimated to have added about 20 to 25 years to the human lifespan.  All the marvelous drugs, diagnostic machines, and new surgical procedures are estimated to have added about 18-20...\n\nGo figure.

These are healthy actions and yes, compared to: 1) eating junk food, 2) not exercising and living a 'fast life' and 3) drinking acidic fluids like coffee and sodas, these can 'slow down' aging.\n\nBest wishes.

Immortality is a tough one.  There is, however, plenty of scientific evidence that aging is in large part genetically programmed. Individuals with certain genetic mutations for example succumb to a premature aging disorder called progeria. Teenagers with this disorder have grey hair, wrinkles, bone degeneration and many other symptoms associated with old age. The fact that these events are genetically controlled, indicates that drugs or genetic therapies can be designed to regulate either slow down or completely inhibit these processes. We would first need to identify the genes that are important.  Studies from a number of groups working in the fruit fly system have used old school breeding strategies to accomplish this.  They raised a colony of fly's separating males and females.  They then allow the last remaining, oldest male and female to breed. Repeat this process 10,000 times over 15 years and what you get is a fly with a life span >3x that of a normal fly (that's 400 years to you and me).  You can then compare the genes that are expressed in your super-fly to that of a normal fruit fly and identify candidate longevity  genes.  This has been done and the human versions of these genes have been identified. The results are fascinating and certainly have the potential to guide therapeutic development.  All of this will not help you if you walk in front of a bus at the spry, young age of 184. Alas immortality is just a dream, rooted in selfishness and a fear of the unknown. Live the life you have to the fullest and try to make a difference in the lives of others.

Its not instant, but Scotland's government health officials just released a Web-based software that allows you to see what you will look like when you get older.\nhttp://www.infoscotland.com/experience/exp_dt_folderlevelAgeingSoftware.jsp?pContentID=101&p_applic=CCC&pMenuID=3&p_service=Content.show&

Take some time, also will do better with age.

You have a high metabolism..be careful, it will slow down as you get older..stop eating junk food, eat foods rich in vitamins, minerals, veggies, whole grains, dairy, junk food will screw up your system faster

The only thing that comes to mind is population growth.  The more people (or whatever organisms) there are, the faster their population grows.

Yes, It is due to activation of oncogenes or external carcinogenic agents. These genes are present in all higher animals. Development of cancer is one of the related sign of aging also.

we should maintain our age!
