No one has ever lasted as long? Really? I saw a program about a year or two ago where they mentioned that an extremely small portion of the general population is actually immune to the effects of HIV and never actually develop full-blown AIDS. This is amazing because a couple of the folks they had on the show were diagnosed with HIV more than 20 years ago, when the whole AIDS epidemic first went public. They looked as healthy as you or I. What's more is that they never received any exotic drug cocktails or other meds to prolong or prevent the diseases progression to AIDS, and didn't even alter their promiscuous or otherwise unhealthy lifestyles--at least immediately. Truly amazing stuff.
Magic, though, has no doubt benefitted from the best and latest medical technology money can buy. He may never develop AIDS (what actually wreaks total havoc on your immune system, leading to your death at the hands of an otherwise relatively mild sickness or infection like a cold or flu), but he will always be HIV-positive regardless of how healthy he looks or feels. So it looks like he'll be plugging and patronizing 24 Hour Fitness Centers for a long time.
