The concept of a lucky hand is a matter of personal belief and cultural tradition, not scientific fact. There's no universally accepted answer to which hand is luckier.
Some cultures believe the left hand is lucky, while others consider the right hand to be so. These beliefs often stem from religious or historical practices. For example, in many Western cultures, the right hand is associated with good fortune and is used for shaking hands, receiving gifts, and performing blessings.
However, in some Asian cultures, the left hand is considered lucky and is used for offering gifts and receiving blessings. This is because the left hand is associated with the heart and is seen as more pure.
Ultimately, the belief in a lucky hand is subjective and based on personal experiences and cultural influences. There's no scientific evidence to support the idea that one hand is inherently luckier than the other.
Conclusion:
The belief in a lucky hand is a cultural phenomenon with no scientific basis. Whether you consider your left or right hand to be luckier is a matter of personal preference and cultural upbringing.
