is this like a slight chance to have a stroke or literally everytime we do it we have a miniature stroke?

What the heck am I hearing!?

So it's NOT natural that I get lightheaded while jacking off for 30 minutes?

Woooooooow Grophen! You foul mouth! do you kiss your mother with those lips? Think of the children's eyes, I'm the children, me.

I'm pretty sure your body isn't being given enough oxygen to do.... exercises with (it usually happens when your heart rate increases and you begin to struggle breathing).

Yes, I kiss my mouth with that mother. And WHO BREATHS WHEN THEY EXERCISE? That's the fastest way to build muscle right? You easy-mode plebians are weird.

You are really annoying Grophen.

Well there are two types of exercises. One where you breathe frequently the other when you exercise with the intention of getting out of breath.

Neither are better as they both have downsides. Anaerobic ('hardly breathing' exercises) can cause you to pass our or if you do it for an unhealthy amount of time you can damage your heart. Aerobic is more of a relaxed form of exercises, they're usually slower than anaerobic exercises but a lot more safe.
For example sprinting for long distances is anaerobic (I don't mean jogging, like literally sprinting for a long time) and lifting weights can be considered aerobic.

This also goes on to the 'exercises' you do grohen.

Could we please sadistically kill grohenbird?
