This sums up the the reality on both sides quite well.
As both Yoav Gallant (former defence minister) and Yair Lapid (opposition leader) have tweeted, it is no surprise that some of the hostages are in this state.
They have been kept in tunnels and above ground, constantly moved during heavy fighting, and presumably had little access to food, as many Gazans faced during the months of war.
Many of the Palestinian prisoners are also returning home looking painfully thin and with stories of being beaten in detention.
One prisoner had to be carried off the Red Cross bus by a medic from the Palestinian Red Crescent earlier today.
Israel too is using release day for its own propaganda purposes. The Palestinian prisoners released today say they were forced to watch a video of the destruction of Gaza before they were freed.
