Following on from my recent post on my ‘mid year report‘ on my bike riding to work, I now calculate a number, that perhaps ought not to be calculated, but I’m going to since I have the following information:

• In the last 4 and half years I’ve ridden my bike to work 578 times
• When I first started riding to work, I bought a 4 pack of soap to use in the shower at work
• Each cake of soap is 95g
• With rare exceptions I’m the only person to use the shower at work
• I’ve just used up the 2nd cake of soap

Which gives me enough information to calculate …

Average amount of soap used per shower = 0.33 grams.

Hmmm… perhaps too much information?

Now 0.33g sounds like a ridiculously small number, but bear in mind that I’m washing off the sweat from a 20 minute bike ride, not the grime from an 8 hour shift down a coal mine, and the soap I’m using isn’t some dainty melt in your hand luxury product, but more of an el-cheapo industrial grade soap mixing it with the high flyers on Mohs scale of hardness.
