I mean, if we get shot or run over then it is probably some kind of blood loss that kills us, if you drown it is lack of oxygen, but how about illnesses, how do they kill?

Depends on the illness/disease in question. frown

Unless its one of the ones which attacks the immune system, then its from complications, such as pneumonia

Usually slowly and painfully as your vital organs shut down, whatever happens I cant imagine the final few minutes as your head looses its blood and the electrical activity slowly ceases is going to be much fun!

On the plus side, you know your never going to have to pay another bill/tax payment/speeding ticket/parking ticket biggrin

Seems like an odd question, something we should know?? beer

Isn't the cause of all death starvation of oxygen to the brain.

Pretty Much, but oxygen is carried in blood, see my previous post....

As to the illness part of the question:

Organ failure - often the heart in the case of high temperatures. Some illnesses cause you to effectively drown in your own juices as it were, others cause internal hemorrhaging and/or bleeding in the brain (compression) but generally lack of oxygen to the brain is ultimately what we all die of.

Why the happy question?

Vital organs shut down, needles to say, heart and lungs are amongst the most vital, if either shuts down, brain goes shortly after.

Exactly, it just depends on how this situation occurs.

that or damage to the brain caused by something other than lack of oxygen

What's the 'death rattle' all about? I don't like the sound of that.

Death is the end point of ageing. Why we age at all is an interesting one.

Cells that are not replaced anymore?

Er apparently.....

ageing is not an unavoidable property of life. Instead, it is the result of a genetic program. Numerous species show very low signs of ageing ("negligible senescence"), the best known being trees like the bristlecone pine (however Dr. Hayflick states that the bristlecone pine has no cells older than 30 years), fish like the sturgeon and the rockfish, invertebrates like the quahog and sea anemone[4] and lobster.[5][6]

In humans and other animals, cellular senescence has been attributed to the shortening of telomeres with each cell cycle; when telomeres become too short, the cells die. The length of telomeres is therefore the "molecular clock," predicted by Hayflick.

Telomere length is maintained in immortal cells (e.g. germ cells and keratinocyte stem cells, but not other skin cell types) by the telomerase enzyme. In the laboratory, mortal cell lines can be immortalized by the activation of their telomerase gene, present in all cells but active in few cell types. Cancerous cells must become immortal to multiply without limit. This important step towards carcinogenesis implies, in 85% of cancers, the reactivation of their telomerase gene by mutation. Since this mutation is rare, the telomere "clock" can be seen as a protective mechanism against cancer.[7] Research has shown that the clock must be located in the nucleus of each cell and there have been reports that the longevity clock might be located in genes on either the first or fourth chromosome of the twenty-three pairs of human chromosomes.

Other genes are known to affect the ageing process, the sirtuin family of genes have been shown to have a significant effect on the lifespan of yeast and nematodes. Over-expression of the RAS2 gene increases lifespan in yeast substantially.

Normally the last breath from lungs filled with fluid, its more of a gargle then a rattle. Had the misfortune to witness it twice from close family members (one of whom died 20/30 years before she should have) frownfrown

I was told the 'death rattle' sounds worse than it is. Drugs were administered to ease it and apparently it is not uncomfortable or painful. How anyone would know I dont know though!

Having lost a significant amount of blood due to internal bleeding, it's not painful when you pass out.
