ELI5: How is Magic Johnson alive?

I mean, not only is he alive, he seems healthier than most 55 year olds. Is this common for someone who has been HIV positive for almost 25 years? Are the meds that good?

If you take ARVs, don't drink or smoke and live healthily, and of course are wealthy enough to have access to whatever medicine and doctors you need, you probably can live out the rest of your life HIV Positive and die of other causes.

Once you have AIDS, though, it is pretty bleak from there on out.
