Impaired glucose tolerance (IGT) is a condition in which blood sugar levels are higher than normal, but not high enough to be diagnosed as diabetes. It is considered a pre-diabetic state, indicating that the body is not processing glucose as efficiently as it should.

Additionally, some people may have difficulty with humor due to language barriers or social norms that discourage playful or light-hearted interactions. Ultimately, humor is subjective and what one person finds funny, another may not, leading to a wide range of responses to comedic content. **

Overall, mountain biking tends to result in a higher calorie expenditure compared to road cycling. **
