The payoff will be HUGE, especially as you keep adding 10% grip strength with every swear.

Assuming an initial grip strength of 100kg[0]:

• After 10 swears, you’ve more than doubled your initial strength (100 * (1.1^10) kg = 260kg)
• After 20 swears, you’re gripping a grand piano
• After 50 swears, you’re gripping a fully grown adult African elephant
• After 100 swears, you’re gripping the Statue of Liberty
• After 500 swears, you’re gripping the planet Mercury
