I just saw a documentary called "pensioner factory" about a business in the US where "the average age of its employees is a staggering 74 years. The staff consists of 35 pensioners aged between 75 and 96."
The company is called vita needle and they make hyperdermic needles and some small stainless parts.
I found it interesting & thought maybe some of you guys would too.
