Chris Bosh Question on his Health Situation

Laker fan here.. so please forgive me for my ignorance. Was going to post this in r/nba but I'd probably be only getting "lol gonna retire blood thinners".

So I mean from a logical standpoint, if it happens more than 1 time, I heard you'd have to be on blood thinners for the rest of your life.. which means he won't be able to play b-ball. It has already happened a 2nd time, but doctors are still saying he'd be able to play.

So what am I missing here? Without a doubt.. if he wouldn't be able to play ever again.. doctors would've told him by now. So what am I missing. I've also read that if they test you and your situation is NOT genetic or something like that.. it won't affect you for the rest of your life. Which Bosh didn't test positive for that.

So... wtf is going on? I'm pretty sure he would've found out if he wouldn't be able to play ever again. And he we are... with optimism that he will play in Oct.
