cardboard hollow blocks.
could've saved lives parang shoebox lang sana tatama sa ulo mo.

conventional or concrete hb? antayin natin si toastedsiops.
living in a condo pala is like living in a house of cards.

No... that is just a false impression of a single incident. Prefab structures like condos and office buildings are as safe or even safer than older more traditional style construction with use of "buhos" and hollow blocks.

It is like saying the old 60s or 70s era cars are safer than current model cars simple because they exhibit less external damage from initial visual inspection.
