Err... you will lose some unknown number of them to "incidentals". I remember some stataticians did the math on how long a human would have generally lived, if we didn't die of old age, and it averaged around 500 years for most of human history that we have enough data for (largely the small part with cities).

Although, that still indicates that you'd probably at most have lost one out of those ten.
