tiring

    Why is riding a bike at the gym more tiring than running but burn way less calories?

    running for 30mins at 6mph (300 calories) vs. biking for 30mins at 100rpm at Level 6 (200 calories)

    After my cat got neutered, he got super-hyper and playful, he is tiring me out...

    ...lol. Is this normal? He would be okay with playing (with me) once or twice a day but now he just ALWAYS wants to play, but I don't have that much free time on my hand that I just play with him all day long! lol. It wasn't until after he got neutered he got extra hyper. Is this normal? Oh and...
