Is age a mitigating factor in determining a defendant's sentence?

Defendant contends that the trial court abused its discretion in denying his Romero motion. He argues that the court should have given greater weight to the length of his sentence, his age (65 at the time of sentencing), and his fragile medical condition (brain lesions, seizures, blackouts and strokes). Advanced age is not necessarily a mitigating factor. (See People v. Strong (2001) 87 Cal.App.4th 328, 332 ["middle age, considered alone, cannot take a defendant outside the spirit of the law; otherwise, the very factor that takes a defendant within the spirit of the lawa lengthy criminal career with at least one serious or violent felonywould have the inevitable consequenceagethat would purportedly take him outside it"].)
