What should be the ideal weight?

However, for example, after the last medical examination, we had to get some to eat and go to doctors, or the average plant weight was ~66 kg.

My grandfather all his adult life weighs about 60 kg, appears to be dry. He worked at the factory from his childhood, watched the north, in general, engaged in physical labor. Deep in retirement, he stumbled on the centurion-pumped men on the armrestling, and survived them all, some 10-15 years younger than him. 85 recently knocked, complains that all the friends-neighbors have died, say, except for the grandmother of peers at all, there is no one to bother about the hungry military childhood. Health and strength are not determined by weight.
