Chicagosledder say whaaaa??? A 65 yr old person shall not need no more than $30k a year to live. You're too old and crippled to do much of anything fun/costly you don't eat much and your house should be paid off. Just my honest opinion. If it were me I'd put the money towards a down payment on a house not a retirement fund for your child.
If you are old and crippled you better have some $ for long-term care costs. Crap - there's a lot of 65 years old having a ball out there now. My Dad is in his 70's and does lots of fishing and golfing.
