Isn't this almost exactly how John "Stumpy" Pepys died?

fought the lawn, and the lawn won

Although in his case it was a conservatory roof. He was fixing his Sky dish because it had gone on the blink and he wanted to watch the football.
I must say if I was Keith Richards, with his track record, I‘d keep well away from glass buildings. Lots of people his age develop a keen interest in gardening - a pleasant and healthy way to while away the autumn years - but I think in his case it should be discouraged.

The thing I always remember about the tragic death of Rod Hull is a cartoon in Private Eye of a crime scene chalk outline of Rod Hull AND his emu.

You're onto something Archie. The drummer out of Toto, Jeff Porcaro, also died from a gardening accident I believe. He had a coronary after inhaling pesticide he was spraying.

Alleged to have mowed the lawn for his father on occasions. Don't do it, lads. Just say no.

Few of the originally reported "facts" were right. He was 61, not 62. And the Stumpy Pepys connection is moot, because it wasn't a greenhouse, or even a conservatory. Just a bog-standard porch. He'd walked into the glass door having had several more than a few, it seems.

The rest is just the same old sad, sad story of a life with nothing left but the memory of former glories.

This (translated) is from El Diario de Mallorca:

Brunkert's friends explained that he was an alcoholic with a serious problem, which had affected his whole life. "He'd been drinking a lot, all day every day, for years. [...] You used to see him walking down to the shops in Colònia de Sant Pere and he was always drunk, staggering around, no matter what time of day it was."

[...]

He had recently put the house where he died, which he had had built in the early 1980s, up for sale. The electricity had been cut off because of unpaid bills. Inside, by the door, there was a bag full of empty cartons of cheap wine, with several more inside. The whole house was a complete mess, piled up with rubbish - except for one corner, like a shrine, where a pristine drumkit was set up, surrounded by ABBA records and memorabilia.

Especially to live. The dream house in the sun all to often palls into cheap drink from dawn to dusk.
On that cheerful note......
