The mortality rates have a lot to do with the health of the patient and how well of a match they can get. Things get tricky because having graft vs hosts disease helps cure the cancer part because it will attack cancer cells before the rest of the body.

The challenge is finding someone who is an exact match and have the genetics that is resistant to HIV. It might work for those lucky few, but people already have challenges finding a match without the HIV criteria.

You only have to take immunosuppressants for a year or two with a bone marrow transplant. The bone marrow will learn to recognize your body after a while.

The real danger is there is about 15 to 50% dying from the treatment itself. It is probably better to use current HIV treatments and only use the bone marrow transplant as a last resort, similar to what they do for cancer.

Targeting a platform with 2% market share where the culture doesn't like paying for software is not a good business strategy.

Things like have a crappy interface and closed ecosystem is not going to stop game developers. Having a small market share and few paying customers will.

You are safe from overpopulation in the developed world, but it is still a major problem for the billions in the developing world.

Bringing billions of people around the world to the middle class is much more difficult than controlling population growth.

Girlfriends are much more time consuming than prostitutes.

Prostitutes aren't going to drag you to dinner, parks, festivals, museums and make you watch a crappy movies with them all the time.

Athletic competition is more exciting when there is a winner.

Marathons have one winner but the thousands of other finishers don't consider themselves failures. Many people think that finishing a marathon means that they accomplished something great despite losing.

Human interest stories is how you draw casual fans into watching a niche sport. You need a story behind the competitors if you want to capture interest. In mainstream sports, you can know the storylines by watching the games on TV,reporters endless debates on ESPN or talking with your coworkers.

American Ninja Warrior doesn't have that same luxury so the producers have to add human interest stories and competitive storylines. This creates drama so that the viewer at home has something to root for or against. Having a bunch of anonymous contestants run an obstacle for purity sake is not going to cut it.

I don't usually watch swimming, but I will watch Michael Phelps go for 7 gold medals. The storyline is what makes it interesting, not the actual sport to the casual fan.

I would rather listen to a lecture about Adam Smith than read 20-30 thousand pages of his work.

Tablets are toys

You give kids iPads, and they will start playing games, checking Facebook, sending messages to classmates and watching Youtube.

Most radiation treatment for cancer is localized so it isn't as big of a risk to the bone marrow..

If they are going to give some one total body irradiation, they will have to give you a stem cell transplant in order for you to survive.

You can't clearly define emotional or financial harm.

Emotional harm can be caused by posting something embarrassing on Facebook. Financial harm can be caused from buying an app.

Open Source works better for some types of software more than others.

Audio software requires using audio engineers and guys who know a lot if math if you want to produce something that can be used professionally. This isn't the type of tasks that the average programmer can tackle.

Everyone talks about Pandora, but it is Youtube is a major streaming service that you can listen to any music on demand. Why buy the song, when you listen to it for free as many times as you want? It's not perfect, but it is a big factor in young listeners music consuming habits.
