This thread is very irresponsible and quite disrespectful to the deceased. The cause of death is pure speculation.

It I a deduction based on published material.
Cardiac arrest is a common cause of death. 
I did not deduce something sensational or scandalous so it is not disrespectful.

Given Sim is a prominent person in our society and appears to have died suddenly the cause of death will be of interest to the public. Naturally people will try to answer what caused his death.

I am just stating what I think is likely.

It is abit strange we all know how Pele the Brazilian soccer star passed away but officially we don't know how our fellow Singaporean Sim passed away.
