The idea of getting a prediction for death seems bizarre, far-fetched, scary and fascinating to me at the same time. However, I would still want to know. Just knowing about the possible scenarios arising in future may in fact help in the early preventive measures like change of diet, lifestyle, medication, etc. From a business perspective, it would be highly beneficial for many professionals including doctors, insurers, health-professionals,etc. Consider this : few years down the line when Google would have commercialized this technology and we ask 'Suggest me some restaurants nearby' and we get directed to specially selected ones based on our individual model. Also, quite possibly it would be a great revenue stream for Google too.
You're braver than me! It's all just a bit too creepy to my little mind! And what if you're in the 5% they get wrong, and you've planned your life on their wrong decision?
