i think we shouldn't add the saiyen into this debate has they are way above anything normal !

Then we shouldn't add mutants to the debate, because they're way stronger than humans. Whoops. Your mistake

they die and come back to life = double their STRENGH
they almost die and are healed = double their strengh
they fight and lose = double their strengh

Their strength does not DOUBLE, where did you come up with that from? They simply get a power-up as if they were training. DOUBLE? Man, do you even watch the anime/read the manga?

again, with the same training ANYONE could be as strong as any DBZ chars !

Ummm......no. The reason why the Saiya-jins are so powerful is because of their race, they are a STRONG race with the ability to raise their power levels almost infinitely and millions of times higher than the strongest non-ki using human. Because of their ability to heal and get stronger, they are naturally stronger after every battle. That is why the Saiya-jins are so strong.

Now, Piccolo is a different story. Piccolo is a Namek-jin, and all Namek-jins have the power to regenerate as long as there head is intact. Therefore, Piccolo has been killed only twice. He also is so strong because of the training provided by North Kaio-sama, the fusion with Nail, and the fusion with Kame-sama. Therefore, Piccolo received a gigantic power-up and is incredibly strong, the strongest member of his race ever.

Now for the humans. 99% of all humans in DBZ cannot use Ki. However, the few of them who can (Tenshinhan, Yamucha, Kuririn, Chiaotzu) get strong, but nowhere near the Saiya-jin standards. No matter how much they try, they'll never be able to increase their power to that level, because #1 they don't have that much energy to begin with and #2 their bodies wouldn't be able to handle that much energy even if they could.

For example, every being in the universe has a maximum power level, a point where they can't get any stronger. When the Rou Dai Kaioshin allows Gohan to go Mystic, he DID NOT GIVE HIM ANY POWER, but merely awakened the power already inside Gohan. This form then allowed Gohan to use all of his power, and bring him to his max. However, no matter how much he tries, he will never be able to get any stronger than he is in his Mystic form. The Rou Dai Kaioshin merely expediated the process.

Therefore, one could conclude that the Saiya-jins have a higher max power level than humans. Humans, as compared to Saiya-jins, have extremely low maximum capacities.

Therefore, the statement taht "with training, anyone can be that strong" is false
