Is Mugabe scared of falling into the grave?

They say a picture is worth a thousand words, one look at this photo of president Mugabe a lot comes to one's mind. Could he have been too slow to get to his feet as everyone stood up? Maybe he tried and failed or he might have fell asleep and Grace was nowhere near to give him a nudge as everyone was stood up? - Do you think our 92-year-old leader could have been scared of falling into the grave as he watched the coffin being lowered down.
