There’s no “safe” number of cigarettes you can smoke per day. Any number of cigarettes can increase your risk of developing cancer.But the more you smoke, the more likely you are to get cancer. A 2021 studyTrusted Source looked at 229,028 Australian participants to estimate how likely people are to develop cancer by age 80,
In the study, only 1% of people who’d never smoked developed lung cancer by age 80. The study found that the risk of developing lung cancer increases to 14% if you smoke cigarettes.If you smoke one to five cigarettes per day, your risk is around 7.7%, and if you smoke more than 35 cigarettes per day, you’ll have a 26.4% chance of developing lung cancer by age 80.Bear in mind that you don’t need to smoke in order to develop smoking-related cancers. Secondhand smoke also increases your risk of developing lung cancer.
Only Those With High IQs Will Spot The Second Horse in This Head Scratching Optical Illusion
An optical illusion is a fun way to challenge your mind. However, some people believe they are also an indicator of intellect. For example, a new brain teaser with a horse can only be solved by “highly intelligent people.”
Solving an Optical Illusion
The optical illusion depicts a fully developed brown and white horse. Viewers are challenged to locate the second horse in the photograph. However, there is a twist: most people are looking for “a second horse” when attempting to solve the optical illusion. However, this optical illusion is supposed to represent intellect because the viewer must think beyond the box to find the second horse.
Although a second horse isn’t pictured, the word “horse” is seemingly hidden in the brown and white horse’s glossy coat.
A Different Perspective
This brain teaser has stumped most people because they’re so focused on finding another horse, that it doesn’t occur to them they could be looking for a word instead. Optical illusions range in how they trick your brain. Some optical illusions test mathematical skills or logic. On the other hand, this horse optical illusion tests observational skills.
