Physiology & Medicine / What are the risks of increasing blood volume to boost athletic performance?

« on: 12/06/2008 16:52:34 »

Examples of performance-enhancing drugs include steroids such as cortisone, as well as natural substances such as the athlete's own blood. Using their own blood to enhance their performance, athletes perform what is known as "blood packing", that is, taking around 2 pints of blood from the body 2 weeks prior to the meet, or match that they are training for, and keeping it stored. The night before the big match, they re-inject the blood back into their bloodstream, thereby having 50% more red blood cells, and enabling them to perform better. This method of performance enhancement is almost impossible to detect, unless it is actually witnessed. After the athlete is done with his or her sport for the day, the two pints are taken out once again and disposed of.

Whoever comes up with these methods is a genious.

Surely this cant be safe? Is it?
Wouldnt the blood vessels burst due to the sheer amount of blood?
Would it be safe for a teen to enact this?

Thanks

Physiology & Medicine / After taking illegal subtances, Is it possible i dont return to my normal state?

« on: 27/05/2008 17:24:15 »

I heard that after taking drugs (illegal ones, cannabis, heroin, cocaine etc) there is a possibility that i dont return to my normal state..

1) Is this true?
2) Does it apply for ALL illegal drugs?
3) Is it permenant?
4) If it is a permenant thing, are there any medications or antibiotics that can bring the person back to a normal state?

Im not a drug user..it was just eating away at my mind..i didnt think something like that could be true..saying as cannabis is legal in holland.

Thanks

Technology / How are moulds made for metal casting, such as making a ring?

« on: 09/05/2008 18:41:00 »

Hey Guys,
I was wondering..could i make my own ring? Im not talking sophicated equipment. Just basic stuff like a Clay mould (Clay from the Pound shop. Or if your American, the Dollar shop) And then melt an iron bar into the mould and let it set?

A few questions..
1) Would my clay mould be able to withstand the heat of the molten iron or would it snap?
2) What temerature does iron start to melt..Cause i was thinking i could use a lighter..but i doubt that would work..I dont have a furnace or a gas cooker, so would i be able to make a makeshift furnace out of brick and use that?

Thanks

New Theories / The physcological side to rape, what do you think?

« on: 14/03/2008 20:32:43 »

I'm not deranged in the head, I just wanted to share my idea with you.

Okay, here it goes.

When i was watching a crime program on the television a few nights ago. I seen an interview with a girl that was raped. I have seen a few other interviews like this on the television before, and on most of them, after the rape, the rapist has said sorry, and apologized. So, why the change of attitude?

Heres my idea. Testosterone controlls the males sexual urges yes? So after the discharge of semen the testosterone levels in the drop and replenish. So maybe the testosterone created the sexual urge to rape in the first place?

Heres my solution. If testosterone creates these urges, cant we just remove it?


Thanks

Note: I'm not an expert in he Field of this and i don't know if this stuff has already been proven or whatever.
