Red Dwarf is coming back

[VectraMan]

but the big problem is Kryton. how can a robot age? More makeup?

It was obvious from Red Dwarf X that although a robot can't age, he can gain a beer belly.

I thought RDX was pretty good; more or less back to its best.

Brill. Trouble is age of the actors. Seen Danny Joules recently in Death in Paradise and he looks ancient! Doubtless the others will be ancient too, which may be ok if the story places them in space for decades but the big problem is Kryton. how can a robot age? More makeup?

PS It's Danny John-Jules.

Would a hologram in a hard light body age? I'd think not, but at the end of series 6 he does.
