Once you attempt the question then PrepInsta explanation will be displayed.
‘Even’, ‘also’ and ‘too’ all nearly mean the same thing but there are differences in their usage. ‘Also’ and ‘too’ are used when talking about an additional object. ‘Even’ is used to talk about a case that is out of the ordinary. Like in this case – it wouldn’t be expected at his age to work hard instead of amuse himself. But in his case, despite being that age, he did. So we use ‘even’. Also note that when using ‘even’ this way, it is used at the beginning of the phrase and not at the end. The correct phrase would then be ‘Even in his middle age’. Since \'to\' is being used as a preposition here and not as an infinitive, the -ing form of the verb can follow \'to\'. The base form is used when \'to\' is the part of an infinitive.Eg: She came to pay the rent.
