Currents in San Francisco Bay

For those that don't believe that the San Francisco Bay can get strong currents, check out this little video clip I took on a paddle last week:

Based on the chart, it is about 30 feet deep at this spot. That is a lot of moving water!
チャートによると深さは10メートルぐらいだそうだ。 流れの水は多いだろう。

Under the Golden Gate Bridge and a few other places (like Yellow Bluff) are know for strong currents. Not this location.

This is where I was at/私はここにいた:

Unintended consequences

I have been thinking about unintended consequences recently. First came up with this government stimulus plan, which includes a lot of road work. Roads generally have finite lives (let's say 20 years, for easy math), at which time major repair work would be needed. I wonder if 20 years from now there will all of a sudden be a lot of roads needing repairs, which undoubtedly we wouldn't have budgeted for?

This also came to another one of Obama's goal - universal health care. I seem to have many friends who would love to retire, have saved a bit of money and all, but aren't retired. When asked, the limiting factor appears to be there need for health coverage. So, if Obama does get universal health care of some sort in place, will we have a sudden surge of folks in their 40s and 50s retiring? Will there be so many that it would impact the economic output of the economy?
