Mr Gopalakrishnan is in good condition along with his guru, as British and US citizens who are educated in their kid stage itself for hands-on training. It is possible to do some simple household repairs but not on high level operations, so as to save 15000 etc which is a bluff. The amount of energy required in Indian style plumbing is enormous. In the USA some technicians will build their own homes. Even in India, masons can do it. Plumber may do plumbing at homes. In the west even removing the ice clog is termed as plumbing and people will in their talk say, did some plumbing. I remember Ramakrishna paramahamsa story: one learned, came and told Ramakrishna, that he spend so much of time, to learn walking over the water; Ramakrishna said that had he given half anna a boatman would have ferried him across; and he wasted his time. The other question is why earth looks flat; he writes after sending the NASA photo (some earlier Q & A) that even from heights the curvature of the earth alone is visible. That shows double jeopardy. He makes mistakes if called stupidity. The other questions are a waste of time to answer. KR IRS 4 8 23
