“Siping” for tire traction in slippery road conditions

Siping is a practice of cutting extra fine slits or cuts to the tire thread surface to improve tire traction during inclement winter weather which often creates slippery road conditions.

According to some tests, siping is known to help a little on snow-covered or icy roads, although it may diminish tire traction when the road is wet or dry. It typically costs you $60 – $80 for a set of four tires (AAA.com/world, Consumer Report). Tire dealerships typically charge around $15 or more to sipe tires. Pros and cons of siping are:

Pros:

Improve a tire’s snow and ice-biting ability in snowy and icy days

Cons:

Invalidate the tire maker’s warranty and cause premature or uneven tire wear
braking distances on wet and dry pavement were a few feet longer
There is no need to modify tire design, since today’s tires already use siping in the way that there are designed and manufactured after rigorous many tests and experiments

Dr. Steven Gundry’s List of Unhealthy Foods

Tomatoes – Vegetables containing Lectins (including eggplants and potatoes)
Beans (can cause food poisoning)
Cashews
Peanuts (can cause colon cancer)
Grains
Brown bread (can increase appetite for bad food)
Meat products from animals who are fed with antibiotics (can destroy good microbes in your stomach)
Diet soda with sweeteners

Good foods – Dark chocolates containing Cocoa (good for heart), walnuts, almonds and coffee with no sugar

Super foods – Prebiotics (for easier digestion), Probiotics (can increase good microbes but not your own in your stomach). Anti-fungal (e.g., PrebioThrive, Bimuno).

Dr. Cary Nelson’s List of Bad Foods to Avoid

Bread containing Azodicarbonamide (a flour bleaching/foaming agent and a dough conditioner) which is illegal in Singapore
Diet soda containing an artificial sweetener (which kills good bacterium in your gut)
Coffee with sugar (can create acid dehydration)
Alcohol (can kill good bacterium in your gut)
Pasteurized juice and milk (can kill good bacterium)

Suggested food – Fermented vegetables (e.g., kimchi), Probiotics (laboratory level).

To prevent digestive problems, we should maintain the microbe balance in our guts (80% good bacterium, 20% bad bacterium).
