Even the initial 10% figure is significant, considering the alternative. If the higher figures are correct for effectiveness, so much the better.

Put into bicycling perspective, how many of us would modify or buy equipment to gain a 10% improvement in our speed and power? I'm betting many of us have already done/spent more for less gain. Such as poring over those rolling resistance reviews to decide which tire offers a 2 Watt advantage over another, and whether it's worth an extra $20 per tire for that gain.

$20. That's about what the flu vaccination cost this year at Walgreen's, for folks without Medicare/Medicaid or insurance.

I'm an idiot for not getting the flu shot this year. Just because I rarely if ever get the flu.

Not only did I put myself at risk, and lost weeks of productivity because I was too sick to accomplish much at a really crucial time in my life, but I also put others at risk by assuming I wouldn't get sick and carry germs around.

I was in health care for years. I should know better.
