Definition: You are given a paragraph, with numbered sentences, and a question. Write the numbers of the sentences needed to answer the given question. Separate multiple sentence numbers with a comma (", "). E.g. "1, 2" would be the correct response if Sent 1 and Sent 2 are needed to answer the given question (do not include sentences that contain no information that is necessary to answer the question). Sort the sentence numbers in an increasing order (i.e., '1, 2', instead of '2, 1'). Your answer should not contain anything than the sentence numbers separated by a comma (e.g. '1, 2, 3, 4'). The given question requires more than one sentence to answer. So, your answer must contain at least one comma (", ").
Input: Paragraph- Sent 1: It's strange how one can write delightedly of the happier moments of life, forgetting the things that one would forget by remembering fully the things one would remember, and suddenly the forgotten, in revenge, rears up to savage the unwary.
Sent 2: So it was as I wrote the preceding.
Sent 3: My heart convulsed, and I left this manuscript for a three-day spree.
Sent 4: Apparently I was so successful that it lasted a week and a half.
Sent 5: Not bad for an eighty-three-year-old, even for one who has his rejuve every month.
Sent 6: And if I can brag and digress so easily, this must not be painful enough to merit a mindwipe, yes?
Sent 7: No. I abandoned these notes to my future self to have the wipe done immediately, thinking that Bernardo Flynn should receive such services when he needed them, even should the need arise at the third hour after midnight.
Sent 8: My mindsmith is not so understanding.
Sent 9: She says I am emotionally a child, to which I reply, "Of course.
Sent 10: Why else would I come to you?"Sent 11: This logic does not soothe her; she says I must wait three weeks.
Sent 12: Three!.
Sent 13: Such is the law.
Sent 14: I say I do not care about law, I care about service and she should care about money.
Sent 15: Enough.
Sent 16: I went on a spree, and it must have been a good one.
Sent 17: I hope the wipe is as successful with my time on Vega IV as my spree was with my time here.
Sent 18: I dimly remember three bedpartners who were probably human, and one that I hope was delirium.
Sent 19: I will not answer the phone for a week, no matter whose face appears on it.
Sent 20: I keep evading the issue. 
Question: How old is the character?.
Output:
5, 7.
