He would of died heart disease if trunks from the future didn't come, also goku died twice, and saiyans age slower than humans... clearly you haven't watched dbz at all.

but Dr. Mez_steve WHY CAN GOKU NOT BREATH IN SPACE WHEN TENS OF THOUSANDS OF OTHER SAIYANS COULD WHEN THEY WENT IN SPACE TO FIGHT FREIZA?

You stopped making sense, gunna go troll someone who makes sense O_o

Saiyans dont die of old age, they die of heart failure.

Also, super man cant breath in space, he doesnt need to breath at all.

and for that matter nothing breaths in space since there is nothing to breath.

Vito Corleone >

Don't fuck with the mafia, superman and goku had to call the Don to get permission to take a shit

Superman only has a power level of 15k or so.

fucking this.

also you didn't use the word "breathe" properly, but still a valid point

Also goku doesn't need a alter ego cuz he isn't a little pussy and just lives like he does and knows he is a boss.

He did die, in the alternate time line that trunks returned to, sorry please do not assume you have anywhere near my knowledge on any subject.
At bolded:
He died to piccolo, cell, raditz, and a few times in dragon ball kai.
Sorry.

There 'are' particles in space that people can breathe. Just not nearly enough to even support one life-form, not to even try to support thousands of fucking saiyans.
