Not a surprise. Pple nowadays play online games all day long
inside a small room. Due to lack of activities, body may not react
fast to environment conditions and may just suffocate to death if
inside a small room with little air convention.
Have you heard of pple who died after sitting in the airplane for
more than 10hours?
Anyway, this is just a sweeping statement. Who knows. That person
isnt inactive. He may just turn out to be a super active guy who
just ran 10km. Go home, bathe, sleep and died.
