Illinois' State Senator who has served on two committees -- one on aging and one on nutrition and human needs -- has assembled a book for all constituents on the problems we know only too well and ignore. If you've read the other literature in books and periodicals, you've already realistically faced the prospects sans options: the inequities and inadequacies of Social Security; food costs on a diminished income (remember that cat food horror story); the neglect of hospitals (two men shoved aside in wheelchairs until they died there) and the gaps in Medicare and Medicaid; and the worst that's yet to come -- the nursing home -- with its isolation, depression, indifference. (Percy is perhaps wrong to criticize as ""cynical"" and self-serving the use of tranquillizing drugs for those who are truly incompetent -- serenity, however acquired, is a blessing.) At the close there's an Action Resource Guide covering SS, taxable income, possible work projects -- volunteer or paid, the not so candy-coated M & M pills, the possibilities of where to live, and state agencies which might offer advice. As it stands, here or in fact, old age is an eyesore we're a long way from treating but Percy has no real specifics in mind.
