In the first modern Olympics there were Olympic medals awarded to literature,sculpture,art,music,etching..Because it was also part of the original Greek Olympics.
Across the years that part has been dropped..but I note that there are still cultural events going on around the country to celebrate these games.It might be nice to bring that aspect back.
Personally I think any sport that requires physical effort or immense skill should be included.So no tiddlywinks or conkers.
But certainly the more events the better IMHO.
