Within each Score, stocks are graded into five groups: A, B, C, D and F. As you might remember from your school days, an A, is better than a B; a B is better than a C; a C is better than a D; and a D is better than an F. As an investor, you want to buy stocks with the highest probability of success. That means you want to buy stocks with a Zacks Rank #1 or #2, Strong Buy or Buy, which also has a score of an A or a B in your personal trading style.
Concentrated peppermint oil can be applied to skin and clothing as a honey bee repellent. Perspiration attracts insects and bees, applying a drop of peppermint oil under your arms will detour the bees away from you.
A further study showed that peppermint oil resulted in 150 minutes of complete protection time against mosquitos, with just 0.1 mL of oil applied on the arms. The researchers noted that after 150 minutes, the efficacy of peppermint oil decreased, and needed to be reapplied.
