Interesting thought ...
Thinking back to the 80s, I cannot remember any healthy sponsors that were huge, at least here in northern Europe. Few people just started running or doing aerobics, but were mostly seen as eccentric nutters lolol. People were wondering: Who gets up early on Sunday morning to run through the woods.

Working out was something for pimps and weirdos when I grew up, let alone those unthinkable "Pflanzenfresser" plant eaters (vegetarian was not even a term) lolol.
Im am so glad that changed, though!!!!
