Walking more maybe enough to keep you healthy. Research indicates that people who walk 7000 steps/day had a 47% lower risk of dying from any cause, a 25% lower risk of developing cardiovascular disease and a 47% lower chance of dying from it and a 38% lower risk of developing dementia.

The paradox of our own ignorance. The unknown unknowns are where the Dunning-Kruger effect comes into play in the worst way. It’s our tendency to overestimate our own skills/knowledge/competence and underestimate our own ignorance

Diesel engine oil contains many additives, making up 15-25% of the total volume. Key additives include detergents, dispersants to manage soot, anti-wear agents, viscosity modifiers, antioxidants, corrosion inhibitors. The additives begin to break down at 5,000 miles. So change your oil at 5000miles

Whilst humans are genetically similar we also share similar genes to all fauna and flora.The statement White
& Black races & chimps share 98-99% of their DNA is a deliberate misconception, the truth is the similarity is only 98-99% of 2% of their protein-coding genes versus the entire genome.
