<human>: Can you give me a shortened version of the text?

There's no way I'm alone with this problem. I'm 5'11" and weigh 165 lbs (I'm a male). I wear medium shirts, and 32 x 32 size pants. I don't consider myself short or tall. Every time I go to buy a shirt, it seems all the sizes remaining are smalls, larges, extra larges, or even extra extra larges. This drives me absolutely mad, especially after finding a shirt I love. Doesn't it makes sense that since the height of our population follows a bell-shaped curve with the medium sized folks making up the majority, that clothes manufacturers should make more mediums to send to retail stores than other sizes? Am I wrong about this? What does reddit know about this phenomenon?
<bot>: Medium sizes are always the first to sell out in retail stores. Stores should order more mediums since it's the most common size.
