people who have multiple degrees

[crowbird]

i see a lot of people here have multiple degrees ( and i am not talking about those who have two bachelors ,a master and maybe a phd)
i mean those who have 4+ 5+ degrees , i am genuinely curious as to why ? does it help you professionally/academically, do people think its overkill ? i am specifically referring to those who have multiple degree across different and unrelated fields, is it just for the joy and challenge of getting a new degree .
