My hamster sleeps all the time and never really comes out to play even at night

[alli624]

I've had my lastest hamster Lisa whos a boy (long story) since October, he was already about ten months then so he'd be about sixteen months now he came from the Rspca. I've had alot of trouble trying to tame him as hes so scared of me, but he always seems to sleep so that makes it impossible to get him out even at night he sleeps and only comes out for food or water I know this because I filmed him for six hours the other night as an experiment to find out what he does at night lol. I've looked at various things on the internet that say hes coming to the end of his life could this be true? I don't think hes unwell as he appears to be healthy but this is the first hamster I've known to behave like this and this is my fourth one now. Can anyone give me any advice as I want a happy hamster now a sad one
