Man casually mowing lawn with massive tornado behind him was "keeping an eye on it"

Women, this is why you live longer than men.

A Canadian bloke has shown his commitment to getting the job done in a widely-shared photo of him mowing the lawn as a mega tornado rages in the background.

Theunis Wessels was pictured working away in his backyard seemingly oblivious to the major hazard looming nearby.

The tornado struck the town of Three Hills in Alberta on Friday evening (local time) but is not thought to have killed anyone.

Mr Wessels told media he was aware of the tornado behind him and was "keeping an eye on it". He insists it was much further away than it appears in the photo.

It looks much closer if you look in the photo, but it was really far away. Well, not really far, far away, but it was far away from us.

The picture has prompted many quips on the internet, with one Twitter user joking "Nothing stops a Canadian from mowing his lawn."
