According to
Life Expectancy Calculator my current lifestyle should give me a good chance of living 99 years. Moreover, if I would be willing to change several things in my life (e.g. starting eating small dose of aspirin every day, cutting my working hours to less than 40 per week, and not working more than 5 days a week) I should be able to live even to 108 years. And that probably would mean living even longer (maybe even 150 or 200 years), as I am convinced that medicine will make a huge leap forward within this time.
