Traditions might fucking kill you

Buy this shirt. Or at the very least, look on it and laugh.  It's a more specific sentiment on traditions.  I don't think they all are useless.  But they should be critiqued.

Here's a good one: the father giving the daughter away at a wedding.  Back when women were property and people worked all the time, the family of the daughter had to get rid of a valuable, working piece of property.  The bride price was paid, the daughter was effectively sold to another family.

Warming up is one directly related to lifting.  In fact, I have talked to no less than five people, in person, who have fucked their shit up doing a warm up set.  Some had it worse than others.  Often unquestioned, yet is it still worth it?

Poor bastard took his warm up too seriously

The latter tradition is one that's testable, thankfully.

I'll keep this brief.  There's all sorts of shit to question.  Depending on your sport, you can question a myriad of things to a great extent.  For lifting, here are some questions you can ask first:

Can I do my goal movement today?
Can I PR in it?
Can I do it more often?
How will I be able to attain the ability to do it more often if I can't?
Can I run myself or should someone else tell me exactly what to do?

The less adaptable you become, the less movement you create.  You know what happens next.
