Visited India four times with son over the last eight years. He's been about 15 times since he was 17. He's a bit wary last year and this as I had a heart attack last year. Hoping to visit again next year. Bit of an oldie now 74. Knees a bit dodgy but otherwise I would hope OK.
Gardening, as a plantsman, exotic, not 'flowers' particularly. Everyday stuff in India, banana, gingers, lantana, bamboo etc not usual in UK
