For stuff like hedges and higher stuff I use a pole trimmer (I call it a 'chainsaw on a stick') which gets the blade a safe distance away from me. For anything aerial, I get the professionals in. I know my limits and wouldn't dream of using a chainsaw without both feet on the ground on extremely stable footing.
Yip, bought one of them since my accident as well. Isn't hind sight a wonderful thing. I also left the pint or so of dried blood on the chain bar as a reminder not to be so stupid in future ☺️
