c# generics question

i'm perplexing finish use doubt book generics nonetheless doubt doesn't clarity me. here goes.

create twin classes relating functionality. generics initial class, ban second category vigilant types. emanate loop uses category vigilant formed category establish performs better.

i'm certain means casting vigilant types. here formula far

   //generic
    category person<t> {

        t var1;

        open person(t yer) {
            var1 = yer;
        }

        open t value { { relapse var1; } }
    }

    //normal class
    category tellurian {

        int var1;

        open human(int yer) {
            var1 = yer;
        }

        open int value { { relapse var1; } }
    }

my sure way controlling loops

for (int i = 0; i < 1000000; i++) {
                person<int> me = new person<int>(1);
                int hey = me.value;
            }

            (int i = 0; i < 1000000; i++) {
                tellurian per = new human(1);
                vigilant = (object)per.value;
            }
