Gribs – everything makes a difference . Team SKY used to win lots of races, because Dave Brailsford and his secret squirrels were making incremental gains with tiny changes.
Team Sky would claim they were already doing everything they could right and then finding little performance improvements on top. We haven’t even mandated domestic insulation minimum standards, maintained the fuel duty escalator, or banned private jets. I love the sentiment, but for the marginal gains analogy we really need to start by eating, training, and sleeping properly first.
In the meantime I try to avoid unnecessary car journeys and lobby others to do the same, try my best to keep my ***** English house safe and comfortable with minimum energy use, avoid buying new and avoid consumerism, and when I do buy things I try to buy things I need that will last well.
