Can someone please correct this short proposal?

In my opinion, you are setting up a very interesting series of documentaries which ?would be of interest to? (depends what you actually mean by the word 'affect') a large number of people of all ages. Please find below my suggestions for four unusual hobbies.

TANGO DANCING
It could be a strange hobby for a man, but this is the point. I have been dancing since I was ten years old. Tango is an incredible (maybe 'incredibly;' - 'incredibly' means that the passion is incredible; 'incredible' means that the dance itself is incredible - either would work - you choose) passionate and intense dance that let people show their deepest feeling. On the other hand it takes huge effort: after ten years of practice I cannot consider myself a good dancer yet.

COLLECT FOSSIL
I collect fossils from (either 'all ages' or 'any age' and from all over the world (you wrote 'word'). I have got around a hundred fossils bought directly from the extraction site or from the internet.

MUSHROOM GROWING
A friend of mine has this incredible attitude (I think that 'attitude' may not bring the correct meaning - do you mean system or way of growing in which case say 'way of') growing mushrooms. He owns some 'yards' is a linear measurement, you need square yards or acres OR hectares - find the definitions - of woodland in which he plants any species of mushroom that can properly survive in those particular weather conditions.

PHOTOGRAPH
Maybe it does not sound as strange as the other, but I am thinking about quantity: one of my friends has twenty thousand photographs collected during his whole life.

These suggestions will be of interest to a large group of people and without any doubt they are the strangest hobbies that you will ever hear.


Many thanks to all of you who will take a few minutes to correct this writing. Bye
