Would the disciples be old enough to hallucinate?

Here's a very quick thought. 46% of seniors tend to have experiences that they perceive as of a dead spouse, and 14% of these experiences are visual ones (an additional 11.6 of them are interactive, despite not being visual and 2.7 are tacile). The question is, however, what would qualify as a senior back in the day? Considering that people only lived until their 40's, would early or late 30 fall into that category? Would the disciples have fallen into this range? My gut feeling is yes, especially since apologists never bring it up, even when they can (especially in the case of Gerald O'collins, here). However, it would be nice to have an actual answer. Does anybody out there know?
