As a disclaimer, I am a lot younger than you, unmarried and unattached.
For myself, my strategy is and I think most likely will be an all-stocks (total market index fund) strategy.
This is because I expect to work as long as possible (no interest in retirement, I love my field). As I continue to save, I will have far more money than I know what to do with. Stocks will therefore give me better long-term returns (30, 40, 50, maybe 60 years) and I won't care about the volatility. (If things drop so much that the investments become worthless, I'll have bigger issues to care about.)
