When I decided that I didn't want an epidural my mom said: «Well you just have such low pain tolerance, and really, what's the point to going through all that pain if you could just have the epidural and relax and watch TV?» (attachmentparenting.org)
Bodybulding is hard work, most of the time it's not pretty or fun, which is why the lazy ones or those with low pain tolerance shouldn't be bothered to try it. (fitnessandpower.com)
Word to the wise: If you prefer a soft massage or have a very low pain tolerance, you should steer clear. (health.com)
