I would imagine you would use carbon to date humans.
Radioactive elements are used to date the age of rocks. Radioactive elements decay according to a known pattern. Scientists can use the elements of that pattern to determine when the rock with the original radioactive element was formed.
feelling or intuition
about 200 hundered years for exsesive use i would say
The run-down area attracted a certain shady element. A new element was discovered at the lab.
In general Tungsten is used in heating elements. Lightbulbs and Oven elements are a common use.
If it has a use by date you are supposed to observe that date. I personally would ignore the use by date and use it

Monday 27 April 2009 Is the correct layout. DO NOT use commas. Commas separate elements of a sentence from each other. A date is a collective element. To use the below would be wrong: Say if you use today's date: Monday, 27 April, 2009, or Monday, April 27th, 2009.
One hundred percent of all humans use air, without which they would die.
There's something wrong with this question. Everything around us is made out of elements. We can't do anything without using a couple of elements. Oxygen might be a good answer. We use some of that from the moment we draw our first breath. But most elements are mixed up, impure. So maybe this is about which was the first "pure", or refined element humans learned to use.
To find out the date
It all depends whether it is a sell by date, use by date, or a best before date. If it is a sell by, then that would be an earlier date than an 'eat by' date so it would probably be OK. If it is a best before, then it probably won't taste as good but will still be safe; if it is after a use by date then it may not be safe so you shouldn't eat it.
that would mean either humans actually use technology to its potential, or the anti-economy destroyed everything of use and humans are now extinct.
A geneticist would use a pedigree to trace the inheritance of traits in humans.
I would call it a symmetrical date.
Many documents are similar in their structure. So instead of having to recreate the same components over and over again, you can create or use a template which will have the standard elements, and then you don't have to repeat them. You can then concentrate on the unique parts. So if it was a memo, for example, It would already have the main headings in such as Date or To or From and any boxes or designs drawn, so all you have to do is type in the actual date, who it is to or from and the message. As the structure is from a template, then all memos would look the same. Avoiding having to do the repetitive elements, saves a lot of time and effort.
