Suddenly thought of what i did over the past week again.
Thinking of it, studying wasnt very much productive.(as usual. raHHHH.)
But definitely, my spiritual life has improved.
Daily morning prayer in church and the 2 night prayer meetings were woah!!
The walk with God has definitely caused me to change my perspective over many things and people.
Even if the ppl ard dunno, i suppose i noe it well enough that the way i think about things and talk have started to change.
Rahh.. i dunno if im making sense. but wells bear with me. hahs.
Anyway im back from SUSU'S party.
Everyone is crazy inhaling Helium to change their voices into this cute chipmunk voice.
But i just cant do it. oh wells. nvm.
Went to google abt it cuz was quite curious.hahs.
Because helium alone is less dense than atmospheric air, it will change the timbre (not pitch) of a person's voice when inhaled.
However, inhaling it from a typical commercial source, such as that used to fill balloons, can be dangerous due to the number of contaminants that may be present.
These could include trace amount of other gases, in addition to aerosolized lubricating oil.
Deeper information: hahs.
A little-known aspect of inhaling helium is how quickly you may lose consciousness due to asphyxia (oxygen deprivation).
During the exchange of gases in the normal breathing process, the blood stream absorbs oxygen from air in the lungs, while carbon dioxide passes from the blood to the air.
When you hold your breath, the exchange of gases slows, as "stale" air in the lungs is no longer replaced by "fresh" air.
This process does not stop instantly, however. Some time will pass before you start to experience serious physical distress.
For example, you would likely have time to pick up and put down an object, walk across a room, or find a chair and sit down before feeling compelled to breathe again.
However, when the lungs are filled with helium, a different process takes over.
Oxygen is actually removed from the blood stream during the exchange of gases.
Depending on how completely oxygen is replaced by helium, you may lose consciousness quickly and without warning—you may literally pass out while still standing.
The usual result is an uncontrolled fall that can cause serious injury, even if normal breathing resumes before brain damage occurs due to lack of oxygen.
Now we know the effects of inhaling helium..i guess it's wiser not to inhale anymore of it from the balloons.
And of course not from the tanks or system itself too, as although chemical reaction does not cause fatal injuries,
the pressure of gas inside the lungs can kill instantly.
Autopsies show that the alveoli (air sacs) in the lungs have been ruptured.
Death follows immediately, as the victims literally drown in their own blood.
Under such circumstances, cardiopulmonary resuscitation is of no avail.
Calculations clearly show that, given the flow rate and pressure available from a helium balloon-filling system, human lungs can be fatally overpressured in a fraction of a second and victims simply do not have time to react.
Scary yea?? ppl nxt time before attempting anything please check the effects first.
Phew that there's no one fainting just now.
Hahs.
Jesus loves me. Yes, i know. XD
