New around here
I know a fellow who after many years of PIFR and twin time decided a "Mix Master Belonga Jesus Christ" was a better way to go, he was past 60 at the time and did very well with the learning. Started on an R22 and now has an R44. I have flown with hime and I woulds say his skills were better than average, but I am a fixed wing guy only. But overall he has taken to it no trouble at all.
Having said that a Newbie at 60+ will need some attitude checks, and that is the issue if he is a smart ass. Otherwise go for it. But as others have said, stick to the good VFR days at least for a few years, then go train some more. Easy does it, coz its easy to drill yaself into the dirt or worse
