I hear you. You are thinking in terms of a safety margin, which is very sensible. My problem is that as interest rates get lower and lower, thanks to the manipulations of central bankers, I get less and less comfortable about using those rates as my hurdle. For while I might be happy with a low return today, because it currently comfortably exceeds that of cash in the bank, who knows what those rates will be 5 or 10 years from now. Especially when one considers that increasing the supply of money today may not result in apparent inflation next year or the year after, but ultimately, printing money is creating monetary inflation. I just don't know when the chickens will come home to roost.

I'm not disagreeing with you. It's just a dilemma for me.
